Aluminum electrolytic capacitors apply a wide range of uses, from consumer electronics, automotive, industrial electronics, to medical and telecom fields. These areas require capacitors with various sizes, capacitance, and other specifications. The UEP1A472MHD aluminum electrolytic capacitor is an excellent choice for a wide variety of applications due to its very high voltage rating and heat resistant construction.

The UEP1A472MHD aluminum electrolytic capacitor is a cylindrical capacitor with an anode composed of aluminum foil layers and the anode is soaked in an electrolyte solution. Its cathode is an aluminum oxide film formed on the anode surface by anodic oxidation. A dielectric layer forms between the anode and the cathode to separate them and to provide the insulation between the two.

The UEP1A472MHD offers a very high voltage rating of 480V, a capacitance of 4700µF, and a top pole temperature rating of 125° Celsius. Its sealing gasket is flame retardant and provides excellent maximum insulation for long life. The UEP1A472MHD has a safety vent and its rated voltage has been tested and certified according to UL 60384-14.

The working principle of aluminum electrolytic capacitors is based on the electrolytic polarization of an electrolytic by the external electric field between anode and cathode. When a potential difference is applied between anode and cathode, an electron-ion flux is created, causing the oxidation of anode and the reduction of cathode, forming the new oxide layer on anode and releasing electrons from the anode, therefore forming an electric double layer on the cathode.

The UEP1A472MHD aluminum electrolytic capacitor is an excellent choice for applications where high reliability, high operating temperature, high ripple current capability and an extended service life is needed. This capacitor is ideal for use in high voltage DC power supplies, power amplifiers, high frequency inverters, motor drive systems, and other applications where wide temperature range and a long lifetime are demanded.
