Re: Ceramin Caps
Chris,
I looked into these caps also, but they just aren't cost effective for a
primary cap. 100 of them in an array of 25 parallel strings of 4 in series
is only .00625 uf at 40 KV. And the ceramic dielectric dissipates more
power (gets HOT) than you want. Look for surplus "snubber" caps in the 1
to 3 KV range which are designed to handle pulses.
