My suggestion is EFC-Wesco in Connecticut.  Bob Fountain is their sales guy.  They have done several custom film capacitors for us to be used in our high voltage power supplies running up to 180 kV.  Granted the cap was not run at the full 180 kV, but 30 kV and 40 kV is not uncommon for us.



My 2 cents.

Subject: [TN] (OT) High Voltage Pulse Caps



Greetings TechNet community,



We're having trouble with a custom cap supplier (first-time 

transaction), which can (not-necessarily) remain nameless.



If I can tap into the collective TN hive-mind:



Has anyone had a good experience with a cap manufacturer that can supply 

custom high energy caps with these type of specs:

Qty (2) Pulse Capacitors

40 kV

12.5 uF

for

20,000 (20 k) Joules Max (pulse)



Similar application:

https://en.wikipedia.org/wiki/Exploding_wire_method



Very low duty cycle (1 or so shots per random day).



Because of the above manufacturer issues, we are also interested in 

close, and not-so-close, temporary substitutes to perform some basic 

system functionality tests.



I'm happy to receive responses off-line, or on TN if you feel others 

would benefit.



Regards,



Chris
