Re: MMC Cap voltage rating ???

Bargain Bags tend to not be suitable for Tesla Coil use. . . .  What 
is the make, model, and part number of the capacitors you've purchased?

The voltage rating used will depend on the type of caps you have.  A 
self-healing, high-current type should be able to use the DV cap 
voltage.  A self-healing, low current type will want significant 
derating to bring the current down to a managale level (more 
strings).  A non-self-healing cap, like mica, will want even more derating.

The AC rating of a 1500V film cap will be around 500VAC depending on 
make and model.

Best regards,
