Working Principle of LKX2E331MESZ25

The LKX2E331MESZ25 aluminum electrolytic capacitor is a kind of electrolytic capacitor, and its structure comprises two electronic conductive plates covered with a layer of insulating aluminum oxide film. The two poles of the capacitor are connected by the conductive pole that serves as both an anode and a cathode, with the anode representing the left terminal of the capacitor and the cathode representing the right terminal of the capacitor. When an electric field is applied to the capacitor, positive ions and negative ions migrate to or from the plates, leading to a potential separation and formation of a dipole field. This dipole field stores energy in the capacitor in the form of an electrostatic field. In addition, the aluminium electrolytic capacitor has advantages of small size, multiple surface layers and small equivalent series resistance which is lower than film capacitors. Therefore, it is widely used in power supply aspect, for example, providing a reasonable impedance of the power supply output circuit after decoupling.
