Aluminum electrolytic capacitors are widely used in many applications. This type of capacitor, with its unique characteristics, is especially suitable for applications such as motor starters, radio receivers, and audio amplifiers that require relatively high input and output capacitances (in the range of microfarads). The 400MXK220MEFCSN25X30 aluminum electrolytic capacitor is a popular choice for these applications.

Application Field

The 400MXK220MEFCSN25X30 aluminum electrolytic capacitor is used in many applications that require high-tolerance powersupplies, such as motor starters, radio receivers, and audio amplifiers. This capacitor has a 330 μF capacitance and works with a rated voltage of 220 VDC. The self-healing capacitance of the 400MXK220MEFCSN25X30 capacitor can protect against overvoltage or short circuits.

Working Principle

An aluminum electrolytic capacitor consists of a cylindrical metal case filled with an electrolyte paste. A pair of rolled-up metal foils, separated by an electrolyte paste, is glued to the edges of the case. The inner surface of the metal foil is covered with an oxide film, which acts as the dielectric material.

The two metal foils act as the plates of an electrical capacitor, and the oxide film is the dielectric. The capacitor generates an electrostatic field when the two plates are charged and a potential difference is set up between them. This potential difference is the capacitance of the capacitor. The 400MXK220MEFCSN25X30 aluminum electrolytic capacitor has a moderate capacitance of 330 μF, which makes it an ideal choice for applications that require relatively high voltage and capacitance.

Conclusion

The 400MXK220MEFCSN25X30 aluminum electrolytic capacitor is a popular choice for applications that require high-tolerance power supplies. It has a moderate capacitance of 330 μF with a rated voltage of 220 VDC. The self-healing capacitance of this capacitor can protect against overvoltage or short circuits. The aluminum electrolytic capacitor’s working principle is based on the creation of an electrostatic field between two plates separated by an electrolyte paste and dielectric oxide film.
