[sdiy] Starter Components - Capacitors

[Chris CROSSKEY]

Polystyrene for 10pf to 1nF in E6
Polyester from 1nF to 1uF in E3
Tantalum from 1uF to 22uF in E3
Some big electrolytics to use as power resevoirs.... say 2200uF at 40 or 63V 
and some 1000uF at 16 or 25V

E6 series is 10, 22, 33, 47, 68, 100, 220, 330 etc
E3 series is 10, 22, 47, 100, 220, 470 etc

If you get offered some cheap caps at bigger than the values for there 
normal range (10uF polyesters, 2n2F polystyrene etc then snap em up :-))
You could replace the polystyrene with silver mica, but I'd avoid ceramic 
until you know where you can get away with it and remember that if you fit 
the tantalums or electrolytics back to front they will explode on power 
up......
