    Where? I could do it for myself,

    For those who aren't convinced that Bill knows enough about search to
    provide suitable links:

    https://www.google.com/search?q=metallized+film+capacitor+construction&udm=2

    https://www.google.com/search?q=metallized+film+capacitor+construction&udm=14

    As a side note, someone made this:
    https://udm14.com/
    But I doubt that that will last many years.

    The basic question was whether the metalisation was any thicker than
    that required to get more than one atom thickness at the thinner points,
    and none of your links seem to answer that explicitily.

    The basic google query says

    AI Overview
    Comparison of Metallized Film Capacitors and Film/Foil ...
    Film capacitor metallization typically involves an ultra-thin layer of aluminum, zinc, or an alloy, measuring roughly 0.02 to 0.1 -|m


    There was some emphasis on the self-healing properties of very thin
    films - when the there is an arc you want it to be able to vapourise all
    the metal in the vicinity without getting the film hot enough to get
    carbonised into a state where it too can conduct - but no discussion of
    metalisation thickness as a pile of atoms.

    but if you want to pose as an expert, here's your chance to shine.

    You didn't shine.

    The self-healing caps usually have a geometric pattern of square cap
    regions connected by tiny fuses. Those are usually made with
    aluminum/zinc composite layers.


    back when I first learned about them - back in 1970 - they didn't.

    The wikipedia article you are presumably relying on does talk about
    "T-shaped sections" for specialised applications, but doesn't suggest
    that this is what is usually meant.

    https://en.wikipedia.org/wiki/Film_capacitor

    You are allowed to look that up and learn.

    I make a habit of it. You didn't post the link you seem to have been
    relying on, and and you don't seem to have learned as much from it as
    you might have done. Your claim that the metalisation can be an
    aluminium/zinc composite strikes me a dubious. The metalisation can be
    either aluminium or zinc, but putting both down on the same film does
    seem to be improbable. Metal-spraying the ends of a capacitor with
    finely divided molten zinc to connect the aluminium films to real wires
    does seem to happen.

    The self-healing properties of evaporated metallic films does imply the
    films are made as thin as they can be - which is to say just thick
    enough that the thinnest areas are just one atom thick. I should ahve
    thought of earlier - I've known about self-healing forever, but don't
    get to think about it all that often.

    This is actually the informative link.

    https://www.capacitorconnect.com/what-are-different-types-of-metallization-used-in-capacitor-films/

    It seems that in some applications it is worth putting down an initial -
    very tin layer of aluminium to give a somewhat thicker layer of zinc, something that is easier to bond to than bare plastic film. The link
    does make the point that zinc films self-heal better than aluminium
    films - it takes less energy to blow it away from the short-circuit path
    - but they do oxidise at room temperature in way that alumniuum films
    don't.

    Plowing through papers published in peer-reviewed journals in one of the tedious tasks one has to master to get a Ph.D. I don't think that that
    link is any more useful than the one I've picked out of your first grab bag.

    I don't disdain people who haven't got a Ph.D. Win Hill started on a
    Ph.D. in chemical physics, but he had better supervision than I had and
    they persuaded him to get a masters degree in electronics instead.

    I am a bit disdainful of people who can't write a concise post that says
    what it needs to say. Academics should be able to manage this, but many
    can't, and it is skill that many have master without getting any
    academic training>

    You didn't post the link you seem to have been relying on, and and you don't seem to have learned as much from it as you might

    either aluminium or zinc, but putting both down on the same film does seem to be improbable. Metal-spraying the ends of a
    capacitor with finely divided molten zinc to connect the aluminium films to real wires does seem to happen.

    The self-healing properties of evaporated metallic films does imply the films are made as thin as they can be - which is to say
    just thick enough that the thinnest areas are just one atom thick. I should ahve thought of earlier - I've known about
    self-healing forever, but don't get to think about it all that often.

    John Larkin made vague and unsupported claims about aluminium and zinc metallisation in plastic film capacitors. He did - more or less

    didn't highlight the link in any way or indicate what the specific
    information meant.

    It is perfectly true that any of us might have come up with that for
    ourselves if we had looked hard enough, but in this particular instance
    he didn't look very hard. He rarely does.

    You did post a link that presented a whole grab-bag of possible sources, but you didn't identify any of them as actually useful,
    so you didn't tell me anything. Even the sloppy nature of your thinking that this revealed (again) has been on show for the past
    twenty years.

    I said that film caps do not use single-atom thick metalization, and
    that some use combined aluminum and zinc metalization. I learned those
    in a few minutes of web searching.

    It wasn't hard to find facts about metalization. The mystery is why
    you couldn't.

    I wonder how really big caps are constructed, like the utility
    power-factor things.

    I used to buy huge oil caps when I was a kid, to pop flashtubes or
    just make loud noises. I'd run them at all the voltage I could make,
    like 25 KV.

    expects more respect than he deserves, and is resentful about not
    getting it.

    Yes but then Bill arrived.
    I'm done with this.

    He injects himself into the conversation, gets rebuked and retreats in a
    tiff.

    Something about power conversion (and inversion), ...,
    not so much the "projection".

    The thread warped into an discussion of metallised film capacitors. You
    had posted a daft idea about making compact high value capacitors by effectively crumpling up the opposed surfaces as matching beds of nails, ignoring the fact that spikes generate field emission current.

    Arc discharges depend on this fact - the discharging surface gets hot
    enough to distort into lots of small but very sharp spikes when
    subjected to a high electric field.

    Common interests are wide and varied,
    everybody has a unique and distinct perspective.

    There's something to appreciate from all the contributors,
    better than the usual dead-internet bot-net,
    and often enough a gentle barb is appreciable a smooth jibe,
    then for the gentlemanly, scholarly, and professional.


    "Don't argue with a pig, both get dirty and the pig likes it."
    "Don't argue with stupidity, it gets stupid and they have
    lots more experience."

    Trapping and dispatching trolls is a common enough exchange
    in plain unmoderated open forums of the voluntary sort.


    I respect elders, even old farts, or as Mark put it one
    time upon retirement, "now I'm retarded".

    It reminds me of the chemistry instructor's lab-coat buttons,
    "old age and experience beats youth and vigor", or, the old
    "hydrogen cyanide is all natural".

    Edward Rawde is easily amused.

    That makes life more enjoyable. Are you ever amused? Certainly not
    here.


    Eb Major has three flats.
    I can find evidence if you want but I don't provide evidence for every
    statement I make because others can either find out for themselves or they >>> may already know.

    John Larkin made vague and unsupported claims about aluminium and zinc
    metallisation in plastic film capacitors. He did - more or less
    accidentally - came up with a link to more specific information, but he
    didn't highlight the link in any way or indicate what the specific
    information meant.

    I said that film caps do not use single-atom thick metalization, and
    that some use combined aluminum and zinc metalization. I learned those
    in a few minutes of web searching.
    It is perfectly true that any of us might have come up with that for
    ourselves if we had looked hard enough, but in this particular instance
    he didn't look very hard. He rarely does.

    It wasn't hard to find facts about metalization. The mystery is why
    you couldn't.

    I certainly could have done, but you'd made the claim - why should I
    bother? When I looked at one of the several links you'd posted, I was
    able to dig out a tolerably coherent exposition of what was actually
    going on, and posted it, which you hadn't done.

    I wonder how really big caps are constructed, like the utility
    power-factor things.

    If you had read the link you posted, you'd have found out.

    The problem with very high voltage differences is that you get corona discharge, so you have to limit the voltage over individual gaps to less
    than about 100V. If you just stack your film layers you can do that.

    There's no explicit DC path between the successive layers, but the
    leakage current rises rapidly (and quasi exponentially) with voltage and
    the leakage currents adjust the DC gradient to a nice even distribution between layers.

    I used to buy huge oil caps when I was a kid, to pop flashtubes or
    just make loud noises. I'd run them at all the voltage I could make,
    like 25 KV.

    The fluid used to fill them was a nasty halogenated hydrocarbon. It got
    phased out decades ago on health grounds.

    Sulphur hexafloride is even better at damping out arc discharges, but it
    is remarkably potent greenhouse gas.

    Weren't we having a conversation here?

    Some of us were, then Edward Rawde horned in. Like John Larkin, he
    expects more respect than he deserves, and is resentful about not
    getting it.

    Yes but then Bill arrived.
    I'm done with this.

    He injects himself into the conversation, gets rebuked and retreats in a
    tiff.

    Something about power conversion (and inversion), ...,
    not so much the "projection".

    The thread warped into an discussion of metallised film capacitors. You
    had posted a daft idea about making compact high value capacitors by
    effectively crumpling up the opposed surfaces as matching beds of nails,
    ignoring the fact that spikes generate field emission current.

    Arc discharges depend on this fact - the discharging surface gets hot
    enough to distort into lots of small but very sharp spikes when
    subjected to a high electric field.

    <snip>


    Aye, it's a simplest sort of idea of an ideal super-capacitor,
    then about the why's and wherefore's.



    There's an idea to introduce a third medium, besides the conductor
    spikes and dielectric fill, to insulate the spikes except the facing
    tips, or for example to give each spike a "base collector".

    It is what it is and does what it does - solid state analog electrical
    devices.

    John Larkin made vague and unsupported claims about aluminium and zinc
    metallisation in plastic film capacitors. He did - more or less
    accidentally - came up with a link to more specific information, but he
    didn't highlight the link in any way or indicate what the specific
    information meant.

    I said that film caps do not use single-atom thick metalization, and
    that some use combined aluminum and zinc metalization. I learned those
    in a few minutes of web searching.
    It is perfectly true that any of us might have come up with that for
    ourselves if we had looked hard enough, but in this particular instance
    he didn't look very hard. He rarely does.

    It wasn't hard to find facts about metalization. The mystery is why
    you couldn't.

    I certainly could have done, but you'd made the claim - why should I bother?

    Er, because you disputed the claim. And got it wrong.

    When I looked at one of the several links you'd posted, I was able to dig out a tolerably coherent exposition of what was actually
    going on, and posted it, which you hadn't done.

    I wonder how really big caps are constructed, like the utility
    power-factor things.

    If you had read the link you posted, you'd have found out.

    The problem with very high voltage differences is that you get corona discharge, so you have to limit the voltage over individual
    gaps to less than about 100V. If you just stack your film layers you can do that.

    There's no explicit DC path between the successive layers, but the leakage current rises rapidly (and quasi exponentially) with
    voltage and the leakage currents adjust the DC gradient to a nice even distribution between layers.

    I used to buy huge oil caps when I was a kid, to pop flashtubes or
    just make loud noises. I'd run them at all the voltage I could make,
    like 25 KV.

    The fluid used to fill them was a nasty halogenated hydrocarbon. It got phased out decades ago on health grounds.

    Sulphur hexafloride is even better at damping out arc discharges, but it is remarkably potent greenhouse gas.

    Er, because you disputed the claim. And got it wrong.

    I didn't actually dispute the claim - I just said that I hadn't heard
    that mixed zinc and aluminium metalisation was ever used.

    After I'd dug into the pile of links that John Larkin had posted -
    apparently without bothering to read any of them - I found one example
    of mixed use - when a thin layer of aluminium metalisation was used to
    provide better substrate for a slightly thicker layer of zinc.

    It's not exactly mixed use - all the aluminium substrate does is provide
    a firmer foundation for the zinc layer that does all the work.

    I didn't "get it wrong" no matter how much you would like to see it that
    way, but rather provoked an eventually more informative answer, not that
    John Larkin contributed all that he might have done to the process.

    It wasn't hard to find facts about metalization. The mystery is why
    you couldn't.

    I certainly could have done, but you'd made the claim - why should I bother?

    Er, because you disputed the claim. And got it wrong.

    I didn't actually dispute the claim - I just said that I hadn't heard that mixed zinc and aluminium metalisation was ever used.

    After I'd dug into the pile of links that John Larkin had posted - apparently without bothering to read any of them - I found one
    example of mixed use - when a thin layer of aluminium metalisation was used to provide better substrate for a slightly thicker
    layer of zinc.

    It's not exactly mixed use - all the aluminium substrate does is provide a firmer foundation for the zinc layer that does all the
    work.

    I didn't "get it wrong" no matter how much you would like to see it that way,

    Of course not Bill. It is clear that you can't be wrong. Even when you are.

    but rather provoked an eventually more informative answer, not that John Larkin contributed all that he might have done to the
    process.

    That's kind of weird. I don't expect "respect" from anybody.
    Well-founded criticism is useful, and I do pay attention to it.

    And your head nearly explodes if they do make a post which implies that you might have been wrong.
    But you show no respect to those whom you perceive to be not as up there as you are.

    I don't like being told that I was wrong when I what I posted was less
    wrong than the post I was responding too, and I'm even less enthusiastic
    about people who do it without posting a shred of justification for the
    claim.

    Here's a further contribution from myself.

    I've no idea who got what from who or what its origin was but if I wanted to know anything about capacitors I'd start here:

    https://www.nthuayu.cn/technology/introduction-to-capacitors-huayu/

    You should know where it came from Company Name: Nantong Huayu
    Electronic Co., Ltd. founded in 1987 in China

    And after a while I'd find myself here:

    https://www.nthuayu.cn/technology/metallized-films/

    Scroll down to metallized electrode.

    I found that information while looking for information in addition to the information JM posted.
    To find it I had to think outside the Google box.

    It pretty much duplicates the information in the link that John May
    posted, and was presumably derived from the same source. I'd suspect
    Mullard from the style - their application data was never as technical
    as the stuff that came from Siemens, and less well grounded in the
    fundamental physics.

    What's missing is any indication that the metalisation goes down in
    isolated islands which have to be bridged to adjacent islands by at
    least two bridges that have to be at least a single atom thick - since
    the metalisation seems to go down as multi-atom crystalites the bridges
    aren't likely to be single atoms. Expressing that in an easily
    comprehensible form for people who don't like thinking about single
    atoms isn't all that easy.

    but rather provoked an eventually more informative answer, not that John Larkin contributed all that he might have done to the
    process.

    Edward Rawde isn't stupid. He's not clever, but he does come up with
    good ideas from time to time. The thread on very low distortion sine
    wave oscillators come to mind - John May did improve on his improvement
    by chopping out several transistors, and I managed to improve a little
    on John May's improved circuit by plugging in an extra transistor and
    going for a bit more bias current. It was very much a joint effort,
    though Edward doesn't seem to see it that way.

    He certainly isn't any kind of sinner, if less collegial than he might
    be. He does share that defect with you.

    LOL the ciruit was almost entirely due to JM, particularly the oscillator.
    I had already got as far as polyphase but JM's oscillator and polyphase rectifier is much better than the circuit I arrived at myself.

    <snipped the amateur psychology>

    As I see it, two interesting things drop out of this.

    One is that those who really are up there don't seem to have these needs, but I don't speak for them.

    The other is that you expect respect, not criticism, from those whom you perceive to be up there ahead of you.

    That's kind of weird. I don't expect "respect" from anybody. Well-founded criticism is useful, and I do pay attention to it.

    And your head nearly explodes if they do make a post which implies that you might have been wrong.
    But you show no respect to those whom you perceive to be not as up there as you are.

    I don't like being told that I was wrong when I what I posted was less wrong than the post I was responding too, and I'm even less
    enthusiastic about people who do it without posting a shred of justification for the claim.

    Here's a further contribution from myself.

    I've no idea who got what from who or what its origin was but if I wanted to know anything about capacitors I'd start here:

    https://www.nthuayu.cn/technology/introduction-to-capacitors-huayu/

    You should know where it came from Company Name: Nantong Huayu Electronic Co., Ltd. founded in 1987 in China

    I can assure you that I'm able to copy/paste from a web site Bill.
    You missed the point, which was that I was curious how the information JM posted can also be found word for word (less the page, figure and table numbers)
    on a Chinese web site. The spelling of aluminium is also interesting.


    And after a while I'd find myself here:

    https://www.nthuayu.cn/technology/metallized-films/

    Scroll down to metallized electrode.

    I found that information while looking for information in addition to the information JM posted.
    To find it I had to think outside the Google box.

    It pretty much duplicates the information in the link that John May posted, and was presumably derived from the same source. I'd
    suspect Mullard from the style - their application data was never as technical as the stuff that came from Siemens, and less well
    grounded in the fundamental physics.

    What's missing is any indication that the metalisation goes down in isolated islands which have to be bridged to adjacent islands
    by at least two bridges that have to be at least a single atom thick - since the metalisation seems to go down as multi-atom
    crystalites the bridges aren't likely to be single atoms. Expressing that in an easily comprehensible form for people who don't
    like thinking about single atoms isn't all that easy.

    but rather provoked an eventually more informative answer, not that John Larkin contributed all that he might have done to the
    process.

    But that isn't what you posted. and you clearly hadn't read the whole of
    my post when you posted that comment. I made the same point about the information matching John May's document, and speculated that it
    orginaly came from Mullard, a British firm, if eventually taken over by Philips, who would have used the European spelling of alumimium, rather
    than the American "aluminum".

    Here's a further contribution from myself.

    I've no idea who got what from who or what its origin was but if I wanted to know anything about capacitors I'd start here:

    https://www.nthuayu.cn/technology/introduction-to-capacitors-huayu/

    You should know where it came from Company Name: Nantong Huayu Electronic Co., Ltd. founded in 1987 in China

    I can assure you that I'm able to copy/paste from a web site Bill.
    You missed the point, which was that I was curious how the information JM
    posted can also be found word for word (less the page, figure and table numbers)
    on a Chinese web site. The spelling of aluminium is also interesting.

    But that isn't what you posted. and you clearly hadn't read the whole of my post when you posted that comment. I made the same
    point about the information matching John May's document, and speculated that it orginaly came from Mullard, a British firm, if
    eventually taken over by Philips, who would have used the European spelling of alumimium, rather than the American "aluminum".

    LOL How do you think I determined that the information JM posted matched
    that web site Bill?

    Who cares? "Determined " is a pretentious choice of word. There are lots
    of ways you could have done it, and you haven't specified which one you
    chose. I thought that the content pretty much matched the content of
    John May's document, but I didn't test it explicitly, and certainly
    didn't "determine" anything.

    Philips application notes tend to be a bit better than that. They may
    have called on their NatLab staff.

    https://en.wikipedia.org/wiki/Philips_Natuurkundig_Laboratorium

    Mullard was owned by Philips from early on, but seems to have stayed
    pretty independent. Their diabolical magnetioc application notes seem to
    have been written by E.C.Snelling and are the worst application notes
    I've ever had to plow through. The Seimens equivalents were definitely superior, and after I'd mastered them I did much better.

    I don't know exactly when Philips stopped making capacitors but it was a long time ago
    and you might find it hard to get anything new which wasn't made in China these days.

    China is in the business of making everything and exporting it
    everywhere. Film capacitors use a variety of plastic films - poly
    propylene seems to be the most popular, and that wasn't developed until
    1951 or widely sold until 1957, which is still long before China could
    have manufactured it.
