Working Principle

An aluminum electrolytic capacitor consists of an anode and a cathode separated by a paper spacer soaked in an electrolyte solution. This electrolyte solution contains ions and acts as the dielectric between the two electrodes. When a voltage is applied across the capacitor, an electric field is created between the anode and the cathode. This field polarizes the molecules in the electrolyte and causes them to accumulate in the space between the electrodes, forming a dielectric layer. This reduces the electric field and provides a path for electron flow between the two electrodes.

When the voltage is removed, the capacitance of the device is decreased due to the reduced accumulation of molecules in the space between the electrodes. The MAL214861221E3 aluminum electrolytic capacitor is known for its low leakage current, stable performance, and long life. The anodized aluminum casing of the capacitor is resistant to wear and tear and therefore ensures reliable performance in harsh environments.
