Aluminum Electrolytic Capacitors

It is a type of capacitors that mainly relies on an aluminum oxide layer in order to initiate and maintain capacitance. It is created by a chemical process that forms a solid dielectric between two layers of aluminum foil. Its capacitance is achieved by forming an oxide layer over the aluminium foil.

MAL211671338E3 Application Field

Aluminum electrolytic capacitors are used in a wide variety of applications, including power supplies, LCD televisions, audio equipment, automotive electronics, telecommunications equipment, and computer motherboards. In general, they are used for smoothing and energy storage to prevent voltage spikes.

MAL211671338E3 Working Principle

When a voltage is applied to the capacitor, a current flows out and charges the capacitance represented by the aluminum oxide layer. The electric field existing between the two layers of aluminum foil alters the shape of the oxide layer, decreasing its thickness and creating a higher capacitance. This capacitance can be reversed and discharged by applying a voltage of opposite polarity.
