Aluminum electrolytic capacitors, often simply abbreviated as electrolytic capacitors, are components used in electronics used for storing electric energy and as a key part of power-supplying circuits, power amplification circuitry and filter networks. Amongst all the varieties available, UPH2W820MHD is one of the more popularly used ones. This article will discuss in depth about its application field and working principle.

UPH2W820MHD is an aluminum electrolytic capacitor specially designed for RFP-FF and LC-EIA agreement design. It is ideal for use in applications that require high ripple current, long life, low equivalent series resistance (ESR) and high capacitance values. As such, it is widely used in DC-DC power converters, DC-AC power converters, automotive electronic power supplies, high-frequency industry, telecommunication equipment, UPS systems, LCD television and flat panel display, IGBT modules, fan motors, home appliances, and industrial motor.

UPH2W820MHD utilizes an electrochemical process to store electric energy. The capacitor utilizes two metal electrodes that are held at a precise distance from each other and separated by a dielectric material, usually aluminum oxide. The metal electrodes form an anode and cathode, while the dielectric material fills in the space between them. When an electric current is applied to the capacitor, it forms an electric field between the electrodes which causes a charge separation, resulting in the storage of energy.

Electric current flows through the capacitor resulting in the charging of the dielectric material. The electric field formed by the stored charge causes the dielectric material to become polarized. This polarization creates a force counteracting the electric current flow and increases the capacitance, or charge capacity of the component. This polarizing effect however decreases with repeated charging and discharging, resulting in a drop in capacitance over time.

To increase the life of UH2W820MHD aluminum electrolytic capacitors, vendors coat the dielectric layer with a special compound that helps resist electric current leakage and reduce or even prevent the polarizing effect, hence increasing the capacitance value and lifetime of the device.

UPH2W820MHD is an aluminum electrolytic capacitor that is widely used for applications requiring high ripple current, long life, low ESR and high capacitance values. Its working principle is that it utilizes an electrochemical process to store electric energy by applying an electric current to create an electric field between the metal electrodes which forces the dielectric material to become polarized, causing charge separation and hence storing energy.
