Don't know how many of you guys frequent other tube diy forums but a post today pointed out that Mouser is beginning to stock some new high capacitance film caps from Wima and Panasonic.
They're pretty reasonably priced and both are available in 100uF plus sizes and up to 1300VDC.
They also seem to be fairly compact.
Here's a link for the Wima

And the Pany's are the EZPE series.

Roll on!

Thanks for that Steve. I'm in the market for some at the moment.

WIMA 100uF 1100V - 50x120mm for $32

Panasonic 100uF 500V for $20.95

...not bad at all.

Sorry for the nub question - but why do the panny's have 4 pins?

The short answer is they really only need two. The rest, although connected to one side or the other, are mostly to help hold down a big heavy cap...John

I was kinda wondering why these two huge manufacturers decided to add high capacitance/high voltage film caps to their line up?
Obviously there's some application that warrants the addition of new assembly lines.
After looking at the data sheets, I noticed an application I've never noticed in one before,.. "Wind Power Systems".
Interesting and cool IMHO.
