UVZ2V470MHD

Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors, commonly known as aluminum-electrolytic capacitors, are polarized electrochemical capacitors whose anode is made of an aluminum foil with an etched surface, covered with an insulating oxide layer and a cathode foil with a porous surface. The electrolyte, which acts as the dielectric (insulator), is poured onto the assembly. This type of capacitor is particularly well suited for applications that require high capacitance and high-frequency characteristics, such as communications equipment and TV sets.

UVZ2V470MHD Application Field and Working Principle

UVZ2V470MHD is a series of aluminum electrolytic capacitors specifically designed to operate in high-frequency switching power supplies. This capacitor is a high-capacitance, long-life device that is able to withstand high ratings of voltage, capacitance, and ripple currents. The product is also designed to operate in temperatures up to +105°C.

The capacitance of these capacitors is sufficient for most high-frequency welding applications, such as those found in DC/DC converters and power supplies. The main use of the UVZ2V470MHD is to provide a low-loss bridge between an AC line and the power supply. It can also be used for small-signal, high-frequency filtering applications for DC circuitry.

The working principle behind the UVZ2V470MHD is that it stores energy in the form of an electric field created by the aluminum oxide layer. The stored energy is then released as a current when an alternating voltage is applied to the capacitor. This current then creates an electromagnetic field, which appears as an inductance on the input of the power supply.

The aluminum oxide layer is porous, which allows the electrolyte to be continuously supplied to the capacitor. This not only ensures a consistent capacitance, but also increases the capacitance as the temperature increases, as the dielectric strength of the electrolyte decreases with an increase in temperature.

The UVZ2V470MHD is a long-life capacitor and is highly recommended for applications where high ripple currents are present. It is also resistant to mechanical vibrations, which is advantageous in certain applications. The UVZ2V470MHD is a rugged, high-performance capacitor that can be used for many applications, including DC/DC converters, audio applications, high-frequency power supplies, and power factor correction.
