Actually, some people (including myself) have had luck running MMC type
capacitors using their DC rated voltage as their AC rated voltage.

I'm building an mmc using panasonic caps from the same group as
the ones spec'd in the terry filter.  the digikey p/n is p10513-nd.
I'm building an mmc to replace the single pulse cap that I killed
in my friends tabletop coil.  its using a 6500v/20ma open frame nst
and the resonant cap is about 8nf.  the rms output is ....  okay
my stupid math skills are haunting me...  is the rms output 6500 x 1.41
or 6500 x 2 x 1.41 ?  the cap i designed is 2 strings of 9 0.033uf 1600v
caps. giving a rating of 14.4kv at 7.5nf ( i think, the plans are in the 
other room. )

the question:
to calc rms output: 6500v x 1.41 = rms output?
I'd like to overrate the mmc so I would get 6500 x 2 for the target rating.

also planning on making the mmc into a cube of sorts due to size 
constraints.  if cooling becomes an issue, I will place a small fan on one 
end of the cube.  the mmc cube will be like this: imagine two strings of 
caps folded length-wise 2 times.  2 wide by 3 high. about a 3" cube.
