Re: [TCML] ANOTHER ONE DOWN, ANOTHER 37667 BITES THE DUST
I smash these caps for run times over 15 minutes with my setup without ever
having a failure.. And yes I'm still around :)
Cheers

Re caps for big coils
The 942C series CDE 2kv 0.15uF cap is the one with all the publicity
largely due early geek group support for bulk buys and lots have been
successfully used. IMHO in bigger arrays (often at lower resonant
frequencies) the CDE 942C series 0.33uF 1.6kV option is more economic.
This cap has better Ipk capabilities and is otherwise similar in spec. For
bigger arrays the much bigger capacitance is more than offset by the small
extra numbers in series required to make the voltage rating.
I've used these CDE 942C type 0.33uF 1600 volts in a 15 in series and 4 of
these strings in parallel (88nF) at 10kVA between 40 and 90 kHz without
problems in relatively short runs (< 2min) See also Robin Copini in
Adelaide Aussie who made a big array of these caps, sadly Robin's WEB
pages appear to no longer be available but there is lots about his
activities in the list archives.
