What are some things to look for when buying a capacitor?

When shopping for a capacitor, look for the appropriate size and type. Different capacitors are designed for specific tasks, and there are many varieties to choose from, such as air capacitors, supercapacitors and mica capacitors.

A capacitor is a small electrical device that is designed to store electricity as energy. The unit contains electrical conductors that store the electricity, though the configuration and style of the unit depends largely on its type. They are frequently used in a broad range of electric circuits, and their purpose ranges from allowing specific types of currents in to regulating the power supply within the circuit.
