I was at a hamfest looking for some mylar caps for a circuit that called
for
them. I got several opinions on how to tell one and finall gave up. Are
there any sure fire ways to identiy a cap as mylar and why are they
bettter
than a silver mica or others. Does anyone have a short chart comparing
the
characteristics? How did we get by before mylar was used?
tnx

Hank -

Non–polarized polyester film (Mylar) capacitors are dipped in a hard epoxy
coating material
and provides excellent protection against moisture.
These type of capacitors are intended for general purpose DC applications.
