Highest capacitance box-style film cap?
 

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?

Hi.Where did you find it?Thank you

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
