Depends a lot on which cap from Maxwell.. hence the questions from 
others about the ratings.  Maxwell has caps that are rated for 1pps and 
others for 1000 pps, for instance.   Voltage reversal has an effect on 
life (TC duty has a lot of reversal... 85-90%). Finally, voltage 
(compared to rated voltage) has an enormous effect.

http://home.earthlink.net/~jimux/hv/caplife.htm has the details.

Lots of folks are pretty successful using a 50kV, 1pps rated cap at 120 
pps and 20kV.. the higher pulse rate (which would shorten life) is more 
than made up by running it at less than 1/2 voltage.
