Aluminum electrolytic capacitors are widely used as key components in modern power electronic applications.UVZ1E220MDH capacitors are types of high voltage aluminum electrolytic capacitors and are designed to meet the most demanding needs for designers who require low power loss. These capacitors are applicable for dc/ac line-filtering, energy storage, class A filter, ac motor and inverter drive, etc.

A UVZ1E220MDH capacitor consists of an anode aluminium foil and electrolyte as the positive electrode, and a distinct cathode foil as the negative electrode. The electrolyte is characterized by its high specific conductivity, supplying high dielectric strength and low ESR (Equivalent Series Resistance) values, essential components to achieve low power losses.

The main component of aluminum electrolytic capacitors are the polarizable anode, the separator and the dielectric. The separator is designed to protect the anode and dielectric from direct electrical contact. The anode is a thin sheet of aluminum foil, which provides the surface for the formation of a thin layer of oxide film, known as the dielectric film . In the absence of an external electric field, the formation of dielectric film can only be maintained by ions diffusing from the electrolyte. When an external electric field is applied, the ions move towards the anode, resulting in the formation of a high dielectric constant, low-loss dielectric film.

The working principle of the UVZ1E220MDH capacitor is based on the principle that the anode and the cathode react with each other under the influence of an external electric field. The interaction between the two electrodes increases the capacitance of the cell, enabling it to store charge and release energy when needed. The capacitance is determined by the size of the electrolyte gap, the surface area of the electrodes and the dielectric constant of the dielectric film.

The application of UVZ1E220MDH capacitor is mainly used in high voltage dc/ac line-filtering, energy storage, class A filter, ac motor and inverter drive. The high voltage it can provide is 450-550V, with low ESR (Equivalent Series Resistance) and high frequency characteristics. The capacitance range is 220-560µF. It has excellent electrical characteristics and is resistant to vibration, shock, moisture and corrosion.

In conclusion,the UVZ1E220MDH capacitor is an ideal component to achieve low power losses. Its application field is mainly based on high voltage dc/ac line-filtering, energy storage, class A filter, ac motor and inverter drive, and has excellent electrical characteristics. It also has a wide capacitance range of 220-560µF and high voltage of 450-550V.
