Working Principle:

MAL211927479E3 aluminum electrolytic capacitor is composed of an electrical system, a dielectric and an electrolyte. The anode is made of pure aluminum foil, the cathode is composed of a layered shell, and the dielectric layer is composed of an oxide film formed on the anode. When the capacitor is used, a DC voltage is applied to the anode and a current is generated. This current will cause an electrochemical reaction to occur at the solid-liquid interface between the anode and the cathode, resulting in the formation of an oxide film on the anode. This oxide film serves as an insulator and prevents current from flowing through the capacitor, so that the impedance of the capacitor is increased and the energy it can store is reduced.

Conclusion:

To sum up, MAL211927479E3 aluminum electrolytic capacitor is widely used in various applications and its working is based on electrochemical reactions. The properties of the oxide film formed on the anode effectively prevent current from flowing through the capacitor and allowing it to store a certain amount of energy.
