Much of this is over my head but assuming normal product
development these systems will be on bicycles eventually.

The MOSFETs mentioned in the article have an Rds(on) resistance of
about 1.86 milliohms for a 100 volt device. Smaller numbers means
more efficient switching and less heat. The existing and competing
technology GaN (gallium nitride) is in the same Rds(on) range. The
difference is that the article talks about a MOSFET while the GaN
device is a HEMT (high electron mobility transistor). There are
advantages and disadvantages for each technology. Whether either is
applicable to bicycle electronics depends on that problems the device
is expected to solve. Offhand, I suspect it might work well for
dynamos, bicycle lighting and ebike motors.

More than you probably wanted to know:
"Why you shouldnAt use Rds(on) to select and compare devices in
switching power converters" <https://epc-co.com/epc/about-epc/gan-talk-blog/post/24670/why-you-shouldn-t-use-rds-on-to-select-and-compare-devices-in-switching-power-converters>

Note: 1 milliohm = one thousandth of an ohm = 0.001 ohms.

To put it simply, lower internal resistance of an electronic device
translates to lower heat generated by the device under the same load (electrical current through the device). Heat is a killer of electronics
- It slows the devices down and physically degrades them. The cooler you
can get the parts to run, the better performance and reliability you can experience.

That aside, I'm not sure I get how Mouser being an electronic components distributor translates into innovation and development for motorsports/drive-train. Mouser doesn't have an electronics design
consulting service - They're basically a Walmart for the electronics
industry. We use them extensively for component sourcing but their
electronics design expertise stops at suggesting alternative parts
(based on parametric equivalents). They have MRP and supply chain
services, but beyond that, you're on your own.

Design innovation comes from partnerships/cooperation between the
development teams and the component manufacturers, not sales/distributor middlemen.

This is exactly what they are claiming:
due to the cooperation with component innovators and drive train
developers, mouser supplies state-of-the-art electronics components,
enabling all of their cooperation partners to stay on the leading edge
of innovations (I guess this sentence is sufficient for a "pass" grade
at "business bullshit 101").

Yes, that's what I was referring to, and yes, "business bullshit 101" :)

Thanks for that.
But Mouser seems to write very nice pres releases!
