Aluminum electrolytic capacitors are widely used in audio equipment, power supplies, and other electrical circuits due to their high capacitance values. The capacitor is composed of two electrodes, an anode and a cathode, placed in an electrolyte solution. The attractive force between the ions within the electrolyte is what creates the capacitance. LKG1V222MESBCK,which belongs to aluminum electrolytic capacitors, is also highly valued for its low leakage current, long life, high operating temperature, and large capacitance values.

Application Field

LKG1V222MESBCK has a wide range of applications, such as telecom equipment, LED lighting systems, SMPS, industrial equipment, medical device, and computer systems, etc. By connecting the capacitor in series and parallel, you can further adjust its capacitance, voltage, ESR, and other parameters. It can be used as a power filter or a voltage stabilizer. Its low equivalent series resistance (ESR) decreases energy waste, especially for power adopters, and provides long-term stability to electronic circuits.

Working Principle

The capacitor is formed by three layers: the anode, the dielectric, and the cathode. The anode material is made of aluminium foil with chemical treated oxide layer on its surface. An electrolyte solution coats the dielectric layer and other components, including manganese dioxide, lactic acid, and other conductive agents. The cathode also contains a foil, but this is formed by a thicker layer of conductive material like aluminium or nickel. Upon applying a voltage to the capacitor, an electrical current will flow between the electrodes, forming a conducting bridge. This current will establish an electric field between the electrodes that will allow the capacitance to store charge.

When a current is applied to the capacitor, the oxide layer of the anode will start to break down, releasing oxygen. This oxygen will react with the other components of the electrolyte solution and form ions. These ions will then “float” around in the electrolyte solution, forming a conductive bridge between the electrodes. This bridge allows current to flow, forming the capacitance.

When the voltage is removed from the capacitor, the ions will return to their original state, which causes the conductive bridge to break down. This breakdown process results in the capacitor\'s ability to store a charge, allowing it to act as a storage device. While the capacitor is in this “storage” state, it will slowly discharge its stored energy.

LKG1V222MESBCK is an ideal choice for applications that require low leakage current, long life, high operating temperature, and large capacitance values. Its ability to store energy makes it a great choice for power filters and voltage stabilizers.
