Hi Ben,

PolyPropylene caps work well in filter design Silver Mica are less
favorable.

I used WIMA caps for my PPG designs in the past. But there are many others
out there.

I tend to use what I have on hand for prototyping but use really good caps
for Clock Pll, Oscillator and Filter design.

Terry
