Plastic: Low dielectric losses
Polyester (Mylar) |
Polypropylene > all good for general purpose audio freq's, active filters, timers
Polystyrene | ( low values)
Mica (silvered) > low loss & stable for RF tuned circuits and Oscillators
Ceramic > Good as RF Bypass, not very stable and non-linear, avoid in audio
many types and TempCo. HiVolt used for for mains noise suppress
Electrolytic: High loss
Aluminium : General purpose PSU and bypass
Tantalum : Low voltage PSU and bypass
Check out Electron Transfer types known as Black Gate (by RubyCon)
good for HiFi PSU and coup[ling
