Aluminum Electrolytic Capacitors are the most commonly used type of electrochemical capacitor. These capacitors have a polarized electric double layer formed at the interface between an anode of aluminum foil covered with an insulating oxide layer and another electrode, the cathode, usually made of a highly conductive material. Aluminum electrolytic capacitors can be used to store energy, correct AC line voltage fluctuations, filter noise, provide decoupling functions, provide electrical charge, and more. The 400VXG120MEFC22X30 is an aluminum electrolytic capacitor that is used in a variety of applications.

Application Field 

The 400VXG120MEFC22X30 aluminum electrolytic capacitor is suitable for operations such as frequency range from 280kHz-300MHz, current from 100V-400V and voltage-frequencies up to 200Hz. This capacitor is widely used to provide power factor correction, power supply filtering, and decoupling capacitance in a number of industrial, aerospace, commercial, and communication applications. The capacitor is also used on printed circuit boards, transformers, and lighting circuits to efficiently filter out noise, smooth out power supply line voltage fluctuations, and to provide a stable power environment for sensitive circuits.

Working Principle 

Aluminum electrolytic capacitors work by forming a double layer of electroconductive material on a flat aluminum electrolyte. This double layer is formed when electrical current passes through the holes in the cathode material, which electrochemically deposits layer of ions on the aluminum electrolyte\'s surface. This double layer acts like a barrier between the anode and cathode, allowing energy to be stored between the two. When an electric field is applied, the voltage of the two plates increases, causing current to flow across the two plates. When the electric field is removed, the energy stored between the two plates is discharged and the plates return to their original positions.

The 400VXG120MEFC22X30 aluminum electrolytic capacitor makes use of this effect to store and discharge energy. Its large capacitance and low equivalent series resistance (ESR) make it ideal for high-frequency and low-voltage applications. Its temperature rating of -40° to 85° C makes it suitable for wide range of applications, especially those requiring a long operational life. Its low ESR rating means it can provide significant filtering for power supply lines, while its high capacitance rating makes it suitable for noise filtering, frequency tuning, and decoupling.

The 400VXG120MEFC22X30 aluminum electrolytic capacitor is a versatile addition to any electrical system and is essential for applications that require reliable energy storage and filtering. The capacitor\'s high capacity and low ESR make it an ideal choice for a variety of high-frequency and low-voltage applications. Its ability to withstand high temperature environments and its long operational life make it an excellent choice for industrial and commercial applications.
