Is this a good pulse experiment capacitor?
« on: July 02, 2024, 06:02:38 PM »
2300V 670uF = 1771J
https://au.mouser.com/ProductDetail/EPCOS-TDK/B25645A2677K003?qs=zW32dvEIR3t6K7ahzM8kFA%3D%3D

2000V 800uF = 1600J
https://au.mouser.com/ProductDetail/EPCOS-TDK/B25680B2807K003?qs=P1JMDcb91o7WsLK2IEJuJA%3D%3D

I just looked for any suitable cap from the major retailers and this looks like the only one. I'll probably never dump that much money on it but it seems really energy dense for its size, I have a 3000V 100uF 450J capacitor that isn't much smaller. Just looking for a general cap to experiment with.

The energy density here is also at the costs of something like current handling, requirements to cooling and thinner distances between foil/film, so more likely to punch through.

I can recommend finding old PFC capacitors of the MKP type and abuse the hell out of them, should perform the same as the ones you listed. Check out one of my latest videos on youtube for that PFC capacitor bank project.
