6 Frequently Asked Questions about “Electrolytic capacitor pin identification”

How do you know if a capacitor has a positive or negative pin?

Meaning they have a positive and negative pin. The pin which is long is the positive pin and the pin which is short is the negative pin. You can also identify the polarity using the negative strip on the capacitor label. As shown in the picture above the negative pin will be directly under the negative symbol.
