220VXG560MEFC30X25 Application Field and Working Principle of Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are widely used in power electronics, automotive electronics, computers, communications, consumer electronics and other electronic fields. The 220VXG560MEFC30X25 electric double layer capacitor, characterized by its excellent high-temperature characteristics, is one of the most popular products in this field. This article will discuss the application field and working principle of this type of aluminum electrolytic capacitor.

Application Field

The 220VXG560MEFC30X25 electric double layer capacitor is used in many applications, such as high-precision adjustable power supply, DC-DC converters, high-frequency power supplies, and battery-free Bluetooth headsets. It can be used for high-precision voltage regulation of DC power supplies, realizing an ultra-low dropout voltage that is only one-seventh that of the conventional regulator. In addition, it can be used in power filters with remarkably low ripple, and in circuits such as oscillators, switching circuits, and signal separating circuits, etc. Moreover, it is used to replace batteries in certain occasions, such as for Bluetooth headsets.

Working Principle

The 220VXG560MEFC30X25 electric double layer capacitor consists of two aluminum foil layers and a separator coated with an electrolyte-based synthesized material. The double layer is held firmly together by a special elastic material, forming an electric double layer with stable capacitance. The surface of the foil electrodes, which acts as the anode and cathode, is electroplated with an oxide film. With this two-layer structure, a local electric field is generated, resulting in a potential difference between the two layers. The presence of this electrical double layer between the two conductive layers serves to store electrical energy.

The 220VXG560MEFC30X25 electric double layer capacitor uses advanced selenium dioxide as its electrolyte, which makes its capacitance stable and virtually unaffected by temperature changes. Its capacitance range is from 100μF to 470μF, with an operating voltage of 220V. It has remarkable high-temperature characteristics, with a maximum operating temperature of +125℃, and its life expectancy of 2000 hours at +85℃. Its long service life makes it an ideal choice in many electronic applications.

Conclusion

The 220VXG560MEFC30X25 electric double layer capacitor belongs to the aluminum electrolytic capacitor family. It is characterized by its excellent high-temperature characteristics and its long service life. It is widely used in high-precision adjustable power supplies, DC-DC converters, high-frequency power supplies, and for replacing batteries in certain applications. Its working principle is based on a two-layer structure consisting of two aluminum foils and a separator coated with an electrolyte-based synthesized material. This creates an electric double layer between the two foil layers where electrical energy is stored.
