Multilayer Ceramic instead of Mica Capacitors
#2

Rich

an NP0 (C0G) cap is a better cap when it comes to stability, so if you could find a cap that is an NP0 with the proper capacitance vs WV, use it. Micas are very good and stable, and due to more capacitance per volume unit and higher WV are preferred in some circuits.
The rest, well, could be use in some places and should not be used anywhere where the stability of Mica is important.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
