Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are widely used in almost all electronic applications for energy storage, signal filtering, and power correction or transient protection. Specifically, the MAL209665821E3 capacitor is a 20,000uF 50V radial-leaded aluminum electrolytic capacitor featuring a solid anode. Its construction and design characteristics allow it to be used in a variety of applications.

Working Principle

An aluminum electrolytic capacitor consists of two aluminum foils with an insulating oxide film in between. To form the oxide layer, the aluminum foils are rolled up and soaked in a solution that contains hydrofluoric acid, sulfuric acid, and water. This creates an anode layer of insulating oxide (dielectric) which is then electrolytically polarized. The dielectric oxide layer is responsible for the capacitor’s capacity the ability to hold a charge.

The anode is connected to the positive terminal of the capacitor and the cathode is connected to the negative terminal. When a voltage is applied to the capacitor, a conduction current of electrons flows from the cathode toward the anode and, due to the capacitance of the oxide layer, a voltage is induced across it.
