Film cap dielectric
Does anyone have an opinion for PPS vs Polyester for film caps?
It's for a stompbox build, not an amp, these are 0.1uF, 63V radial caps.
The PPS is more expensive, about twice the price of Poly, and it has a higher max operating temp (125 vs 105C)
Really I am wondering about the sound; would appreciate any thoughts if anyone has used the PPS.
Thanks!

I would say I'd be surprised if you could tell the difference, but read this: https://en.wikipedia.org/wiki/Film_capa ... capacitorscrgfrench wrote: ↑Fri 07/19/19 1:23 pmDoes anyone have an opinion for PPS vs Polyester for film caps?

Both (and other) types are listed. That wiki implies that you may find more stability and better quality with the PPS. Whether or not that's noticeable in a pedal is a different story, and obviously the temperature ratings don't really matter either. If your pedal is getting that hot, it's probably mostly melted anyway, and your foot is on fire.

Re: Film cap dielectric
Yeah I'm not too concerned with the temp rating, I think I'll stick with the polyesters. Thanks!
