C10?

[grungymike]

While rummaging thru the Mouser catalog looking for a cap to pick for C10, I realized that due to the size, it looked like I was going to have to use three 330uF or four 220uF caps in order to have at least a 250 volt limit, or even more caps for a 350 volt ceiling. Every HH pcb design I've studied shows only one cap which leads me to ask what voltage rating that cap really has to be. I'm trying to design a board that can support a 20-50uS transmit pulse width, which should create up to a 320 volt spike max. I've got a funny feeling I'm missing a point somewhere, any advice?

This cap doesn't see the flyback, just +12V. I'm using a 25V electrolytic, but 16V should be fine.

oops

Got it.

Thanks for your patience...
