Highest capacitance box-style film cap?

lil' knight · 27th August 2011, 09:07 AM

I'm wondering which is the highest capacitance box-style film cap out there in the market? The best one I could find is is the Wima MKS4 100uf.

Any other option that I should pay attention to?

WIMA MKS is metalized polyester, and many are coming around to the idea that polyester (Mylar) caps can create distortion. (See Douglas Self, f.ex.)

what application? - for PS basically who cares about anything other than LCR? - maybe if you have zero or worse PSRR you could care about microphonics

you could actually read Bateman articles closely - Mylar as a dielectric isn't the biggest probelem re measureable distortion - using thicker (higer V rating) films and foil electrode construction keeps even Mylar diwstortions in the parts-per-million range for his test conditions
