NPO cap markings?
 

A while back I got the NORCAL capacitor kit. Very useful. But I've
forgotten how the NPO caps are marked. Does the black mark at the
top indicate NPO?

Yes ( In all the ones I know of, at any rate.)

It sounds like you just need to know for this one kit, but the designation
"C0G" also indicates a zero temperature coefficient, it's just a different
nomenclature than used with NP0.

COG is the modern designation. It replaced NPO about 15-20 years ago.

I have no idea why.
