Hello,

I found a lot of a few of what appear to be mica capacitors made by Cornell-Dublier. They look like the standard molded domino cap except smaller and the dots are devoid of color.

Each cap is inked with CM15C and C-D type 22 is stamped into the case.
151G03

Does anyone know how to identify capacity and voltage rating?

Thanks

First, check them with an ohm meter to make sure they are not resistors in that package.

Those are definitely capacitors-- scroll down to page 13 for info on deciphering those markings:

That's neat.

It shows some color codes I've never seen.
I would have thought that impossible.

Thanks.

Thanks Peter,

That is one collection I want to print out. For when the computers don't work any more.
