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?
