Aluminum Electrolytic Capacitors

An aluminum electrolytic capacitor is an electrical component that uses an electrolyte – usually a type of organic solvent with anionic characteristics – to store energy. It is part of the family of capacitors and is typically used for applications that require high voltages, fast switching speeds, high capacitance and minimal leakage currents. Aluminum electrolytic capacitors have a wide range of applications in energy storage, filtering and signal processing, and are used in consumer electronics, automotive, telecommunications, power electronics, and industrial electronics.

400VXR180MEFC22X50 Application Field and Working Principle

The 400VXR180MEFC22X50 aluminum electrolytic capacitor is a cylindrical, two terminal capacitor with a working voltage of 400 volts (VAC). It is designed to provide long service life and high reliability in low-voltage DC applications such as power conversion, motor control, automotive and security systems. The capacitance value is 180 microfarads (μF). This translates to an energy storage capacity of up to 3.6 joules (J).

The 400VXR180MEFC22X50 capacitor is constructed using aluminum foil and paper dielectric. The dielectric material is impregnated with a conducting material such as graphite, which minimizes the electrical losses in the capacitor. The two aluminum plates of the capacitor are separated by an electrolyte that contains ions which allow current flow through it. When a voltage is applied to the aluminum plates, the ions migrate to the positive plate, creating a charge differential, and the capacitor stores charge.

The aluminum electrolytic capacitor is equipped with a protective metal oxide film coating that helps to eliminate short-circuits caused by the formation of pins or other conductive contaminants. It also helps to reduce energy losses and ensures that the capacitor can withstand high temperatures.

The 400VXR180MEFC22X50 capacitor has various applications in the electronics industry. It is used for power supply smoothing and energy storage, such as in the DC-DC converters of laptop computers. It can also be used in motor control, automotive and security systems. The capacitor is also suitable for use in low-voltage high-current switchgear and power factor correction circuits.

In conclusion, the 400VXR180MEFC22X50 aluminum electrolytic capacitor is ideally suited for applications that require high voltages, high capacitance and fast switching speeds. The capacitor is constructed using aluminum foil and paper dielectric, and is coated with a metal oxide film that ensures a high level of safety and reliability. The capacitor is widely used in the electronics industry for energy storage, filtering and signal processing.
