Re: Another MMC capacitor?
Hello, Jim, Andy,
I currently use an MMC using .22µF 1250VDC polyester caps. I've lost one
cap out of 75 to a what appeared to be an over current failure, but I
expected it as I am only using 3 strings with a 12kV 60mA NST, and at
that it was only after a long run. Otherwise they have performed fine.
I'd go for it and buy the cheap caps, Andy.
