[sdiy] Walt Jung and Richard Marsh's Capacitors article

[Happy Harry]

I can't agree...

Polystyrene, Polypropylene, and Teflon caps come out
"on top" because they are physically superior dielectrics.
Caps made with them have less "parasitic" elements that you
do NOT want in a capacitor.

OTOH... All other cap types have their places... some are much
smaller, some excel at high temperatures, most are less expensive.

You have to make an informed choice.  Would you use a teflon cap
for a power supply filter ???   MAYBE... if you are building a spacecraft 
and the nearest repair depot is 15 million miles away...
(obviously PRICE is no object...)

But usually... no, I'll take the electrolytic. Thanks.
