Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are electrical components which use an oxide covered aluminum plate as the anode, a liquid or solid electrolyte as the cathode, and a separator to store an electric charge. They are widely used in both surface mount and through-hole applications, from power supplies to audio and communications applications. As their wide range of capabilities and sizes make them suitable for a variety of uses, there is a great choice of aluminum electrolytic capacitors available for different applications.

ESMQ251VSN681MP45S Working Principle

The ESMQ251VSN681MP45S stores energy in the electric double layer formed on the surface of the anode material, the aluminum plate. This double layer is formed by an ionic current, which is generated between the anode and cathode. The charging and discharging of the capacitor is controlled by the external electric circuit and the current through it. When a positive voltage is applied to the anode, the ions of the electrolyte travel towards the anode and bind to it. As the ions bind to the anode, the electric double layer is created and electric charges are stored.

When a negative voltage is then applied to the anode, the electric double layer is decreased, and the capacitor is discharged. This operation is repeated as long as the voltage remains constant and an electric current is present in the external circuit. With its high capacity and low loss in energy storage, the ESMQ251VSN681MP45S is able to provide a significant energy and power reserve for a broad range of applications.
