Aluminum electrolytic capacitors are widely used in circuits as energy storage devices due to their large capacitance, high temperature stability, low cost, small size, long service life and wide voltage range. With the rapid development of modern electronic technology, aluminum electrolytic capacitors have found wide application in various high-tech fields. UPJ2E220MHD is one of the most famous aluminum electrolytic capacitors.

UPJ2E220MHD is an electrolytic capacitor with excellent performance. It is made of aluminum foil as anode and cathode, an insoluble electrolyte and a protective shell. The shell is usually an amorphous pressure molding (AED) shell. The anodic aluminum foil is formed by electrolytic oxidation. The electrodes of the aluminum electrolytic capacitor are pressed into the shell body, combined with the sealing ring and the end cap, and then sealed with epoxy resin or silicone compound at the end. In this way, all the components of the aluminum electrolytic capacitor are sealed in a sealed space.

Applied in many fields, UPJ2E220MHD aluminum electrolytic capacitors show their excellent performance and versatility. In power electronics, it can be used in switching mode power supplies and inverters, output filters, snubbers, reactors, and boost circuits. In the communication industry, it is used as a transmission line, a filter circuit, a buffer circuit, and an overvoltage protection circuit. In the field of consumer electronics, it can be used in electronic ballasts, AC-DC converters, high-frequency inverters, and various signal output filters. In addition, it is also widely used in lighting, medical and military control, and power system.

The working principle of UPJ2E220MHD aluminum electrolytic capacitors is based on the principle of electrochemical capacitance. The aluminum foil of different centers has a thin film of oxide layer at its electrode. Because of the different properties of the oxide subsurface, the charge potential between the two electrodes is different, and this potential difference can store energy, forming a voltage division on the capacitor. This stored energy can be quickly released when the capacitor is charged or discharged. When the capacitor is charged or discharged, an electric field is generated on the surface of the dielectric, resulting in the polarization of the dielectric and the current of the capacitor.

UPJ2E220MHD aluminum electrolytic capacitors are highly valued by users for their perfect performance, long operating life, wide application field and convenient use. Therefore, it is becoming increasingly popular in the research and development of new products, and its wide application in electronics has also increased.
