Topband: AC line bypass capacitors

[Charlie Cunningham]

Hi, Jim

Well those are the class of capacitors that I was referring to and we used
them in electricity meters that had to operate from line voltages as high as
480 VAC - high-line -or 530 VAC, and of course cope with the hellish spikes
and surges  on the line side of the meters. And you are correct, they are
designed to with stand VERY high voltage spikes without breaking down.

There is a particular class of bypass capacitor required for the AC line,
because it is subject to HV spikes from the power system. They are standard
parts, rated specifically for 3-6 kV. buy from Newark, Allied, Digikey, etc.
I don't recall the nomenclature off the top of my head, but it's in
