I have a couple 5.5VDC 0.33 FARAD caps. They're very small and have a tiny arrow on the sides. I have no idea which side is the positive pole. There is the aluminum case and one end resembles the bump of a positive post on a battery. The picture has the aluminum case facing downward and the arrow points upward. No sense in assuming up is the positive post; so anyone KNOW what the arrow is telling me?

 

Hello,

Have a look at the datasheet.

Thanks bertus, arrows point to the negative side. Wasn't sure, and if I were to guess I would have guessed wrong.

The arrows on electrolytic caps point to the negative terminal, so at least that’s consistent.
