Aluminium electrolytic capacitors are widely used in electrical and electronic systems, from consumer electronics and computers to automotive systems and industrial applications. The 400HXG120MEFC22X30 is a type of aluminium electrolytic capacitor used in various applications. It has a long service life, high capacity, and high temperature resistance. This article will explore the application fields and working principle of the 400HXG120MEFC22X30 aluminium electrolytic capacitor.

Application fields

The 400HXG120MEFC22X30 aluminium electrolytic capacitor is a high temperature, long life, high capacity capacitor, ideal for harsh industrial and automotive environment. It is particularly suitable for industrial applications, such as welding machines, power tools, motor drives, electronic instruments, high power and high current applications. In transportation, the 400HXG120MEFC22X30 capacitor is also used for controlling voltage and current in automotive and marine systems. It is also used in consumer electronic equipment, including personal computers and portable audio/video players.

Working principle

The 400HXG120MEFC22X30 aluminium electrolytic capacitor works on the principle of electrolytic double-layer capacitance. In this type of capacitor, two metal electrodes are immersed in an electrolyte solution. These electrodes are separated by an insulating dielectric layer. When a voltage is applied to the electrodes, an electric charge is stored in the liquid electrolyte. The positive electrode attracts the negative ions of the electrolyte, while the negative electrode attracts the positive ions. This creates a double-layer of charge in the capacitor, resulting in an increased capacitance.

The 400HXG120MEFC22X30 aluminium electrolytic capacitor is a polarized capacitor, meaning that the voltage must be applied in the correct polarity to achieve the right capacitance. The capacitor is designed with a safety vent, which prevents damage to the components in the case of overheating. The capacitor will also self-heal if the electrical current is reversed, allowing it to be used in circuits with alternating current.

The 400HXG120MEFC22X30 aluminium electrolytic capacitor is a versatile component, capable of dealing with high temperatures and high power. The long-life design makes it ideal for industrial, automotive, and consumer electronics applications where performance and reliability are essential.
