DoN.

I was curious and checked the temperature change of several types of
caps with a Boonton meter. Baked-bean micas changed perhaps 5% from
ice water to a heat gun blast. Multilayer ceramics dropped about in
half when heated, tantalums much more. The 1% metal film resistors
that company used for everything didn't change much at all.

1% metal film chip resistors are a miracle of the
modern world. What else in the world costs 3 for
a penny and has 1% accuracy?
