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?
In our particular case, we use the higher DC rating. Since we do not
use our coils 8000+ hours per year, the decreased life due to high AC
voltages will not matter to us.
I know from my some of my other little projects involving DC(5-12V)
that reversing the polarity on a cap results in failure.
They are "polarized caps that have a definite (+) and (-). The film
caps we use do not care about polarity.
