MMC Capacitors from Dr. R.

Original poster: "S&JY" <youngsters@xxxxxxxxxxxxxxx>


For those contemplating buying either the 0.1uF 3KV or 0.15uF 2KV caps from
RRC, here is some food for thought.

At rated max volts, which caps will give you more bang for the buck?  Let's
do the calculations:  Joules = 0.5*C*V*V.  The 2 KV cap will store 0.45
Joule, and the 3 KV cap
will store 0.3 Joule.  Ya gotta love the V^2 factor!

Clearly for the same cost, the 3 KV caps are a much
better bargain.  Saying it another way, your MMC will cost significantly
less if made with the 3 KV caps.
