Re: Huge MMC?

Hi,

MMC caps can easily withstand twice their rated voltage.  So you can put
3200 volts on a 1600 volt caps for special stuff.  However, the quarter
shrinker needs like 100uF I think, so you would need many many caps or many
big snubbers.  Probably in that size, the surplus commercial caps are by
far the best.  for a single pulse discharge application, MMC caps are
probably overkill.  Just the old oil/paper/poly caps do that very well at a
vastly reduced cost.

Cheers,
