Re: Terry's DRSSTC - All Ready!! - MMC rating

Terry, you had tested them again in May of 2003, actually:

Looks like 15+Amp at 10C rise in that test, which ought to reduce your temp rise a fair bit. :)

Hi Mark,

I just picked up the 13.5Arms off the data sheets...  I had long forgotten
that I tested them to 8 amps back in 2000...

The caps seem smaller (less diameter these days to me too).  I know that
there was some industry wide change to the films about 2 years ago that
raised there temperature ratings.  So maybe CD and the rest figured
something out that helps them run at higher currents these days.

I will have to try to retest them sometime to see if they have indeed
improved something.

What is it about your configuration that allows them to tolerate a higher
current than the rating you measured a couple years ago?  Frequency?

The maximum RMS current they can see in the present configuration is 19.4 amps as opposed to their 13.5 rating. That gives a temp rise of

(19.4 / 13.5)^2 x 10 = 21C
