Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are one of the most commonly used capacitors in electronic equipment. They are used in a wide variety of applications, from controlling the voltage in a power supply to providing uniform current across a circuit. Despite their wide applications, all aluminum electrolytic capacitors work on the same principle.

400MXH390MEFCSN22X55 Application Field

The 400MXH390MEFCSN22X55 aluminum electrolytic capacitor is a solid-state, cylindrical capacitor with a voltage rating of 400 V and a maximum operating temperature of 105°C. It is commonly used in power supplies, motor drives, UPS systems, inverters, and in motor control applications. This capacitor is most often used in commercial and industrial systems that require high voltage and reliable performance.

400MXH390MEFCSN22X55 Working Principle

Aluminum electrolytic capacitors work by using two plates, an aluminum anode and a coated aluminum cathode, separated by a thin and porous oxide film. The oxide film is the dielectric medium between the two plates. When a voltage is applied across the plates, the aluminum anode will release electrons while the aluminum oxide cathode will absorb them. This creates a potential difference across the plates, which stores energy and allows for the capacitor to operate.

The oxide film has its own unique properties and can be tuned to have different characteristics. By changing the composition of the oxide film, the capacitance, linearity, and other characteristics such as temperature stability can be adjusted.

Conclusion

The 400MXH390MEFCSN22X55 aluminum electrolytic capacitor is a compact, reliable, and rugged component that is largely used in a variety of power supply and motor control applications. It operates on the same principle of most aluminum electrolytic capacitors, which is by utilizing two plates, an aluminum anode and a coated aluminum cathode, separated by a thin and porous oxide film.
