Sure. Use a COG if it makes you feel better. I think COG are ceramic, and they do cost more, which must mean they are "better". However, I really do not know whether stacked film capacitors perform well at RF frequencies. You should be able to find a data sheet somewhere. You could use a Dueland costing hundreds of dollars in that application, and it would be less good than using a ceramic. The idea is to filter RF, not to make violins sound better. This is with reference to either bypassing a rectifier diode or bypassing the voltage inputs to an IC or sometimes quelling oscillations elsewhere. By the way, with a Schottky rectifier diode you do not need the bypass ceramic capacitor.

- Yes, the OPA 2134 and OPA 2604 are pretty good. - Cougar 14:55:55 06/10/16 (2)
