Capacitor voltage - AC or DC



Original poster: "Dirk Stubbs" <dirk@xxxxxxxxxxxxxx>

Hello all

I am building my first coil using a NST 15kv/30mA. With all the research, I have been seeing people use these MMC capacitor arrays but I have a question. Usually all these capacitors, that coilers are using are DC rated but isn't there supply voltage AC? Does this affect the capacitor?

I know from my some of my other little projects involving DC(5-12V) that reversing the polarity on a cap results in failure.

Thanks,

Dirk
