Aluminum Electrolytic Capacitors UPW2E2R2MPH Application Field and Working Principle

Aluminum electrolytic capacitor is a kind of capacitor, which is mainly used to store and release a large amount of energy in small electric field. It is widely used in many areas of the electrical system, such as high frequency switching power supply, communication devices, charging and discharging devices, etc. There are many types of aluminum electrolytic capacitor on the market, such as UPW2E2R2MPH.

What is UPW2E2R2MPH?

UPW2E2R2MPH is a cylindrical aluminum electrolytic capacitor with external high-strength epoxy resin encapsulated. It has been widely used in wide range of operating temperature from -40~105℃, and in high reliability applications like mature power supply, DC to AC inversion equipment, communication system, instrument and testing equipments. Compared with other electrolytic capacitors, UPW2E2R2MPH has a longer life, higher temperature, and lower ESR (equivalent series resistance).

The Working Principle of UPW2E2R2MPH

The working principle of UPW2E2R2MPH aluminum electrolytic capacitor is a combination of electrolyte dielectric conductivity and physical properties of metal electrode. The electrostatic capacity of this kind of capacitor is composed of two parts, one is the physics capacitance of the metal system, the other part comes from the dielectric constant of the electrolyte. The electrostatic capacity are formed by two aluminum foils with different chemical properties, which are treated by special surface treatment, forming an anode and a cathode. The anode aluminum foil is oxidized, and the oxide layer formed on the surface, corresponding to the electrolytic solution, can be seen as a dielectric material, which forms an electric double layer with an anion solution layer and a cation solution layer. The electric field across the electric double layer is the real electrostatic capacity of UPW2E2R2MPH aluminum electrolytic capacitor. The working principle of UPW2E2R2MPH aluminum electrolytic capacitor is that when AC is applied between the two electrodes, a dielectric polarization occurs in the electrolyte, which further forms an electric double layer, which stores electric energy in the form of electrostatic energy. The energy released by the electric double layer during the discharging period is equal to the energy stored in the electric double layer during the charging period.

The Application Field of UPW2E2R2MPH

UPW2E2R2MPH aluminum electrolytic capacitor is mainly used in power electronics and related application fields to meet the requirements of energy storage and release. For example, it can be used in switch power supply, DC-AC inversion device, rectifier, communication system, and test equipment. It was widely adopted with its strict parameters like lifespan, temperature, voltage, and capacity requirement. Besides, it can also be used in aviation and space applications and other high reliability fields.
