Title: which is which on cap
Post by: KB5MD on August 05, 2013, 09:37:40 PM
How does one determine positive and negative on this type of capacitor?
Is it the small indentation near the bottom of the case and if so, is it
positive or negative?  See pdf attachment below.

The terminal with the pointy black hat is + ;)

Nah, just kidding.

It looks like an oil cap, non-polarized.

73DG

If it's polarized one of those leads, most likely, will be attached to the case. Ohm it out. If not DG is probably right.
