MAL210618332E3 capacitors are mainly used in power supplies and energy storage circuits. Its wide capacitance range (10uF ~ 10000uF) makes it suitable for smoothing, transient suppression, decoupling, and energy storage applications. The desktop PC power supply is one example of where MAL210618332E3 capacitors are most often used. The high capacitance values are particularly suitable for the switching power supplies and controllers which demands high levels of energy storage and filtering.

MAL210618332E3 capacitors are also widely used in communication networks, automotive electronic systems, remote sensing systems, and lighting systems.

Working Principle

The MAL210618332E3 capacitor consists of two metal plates that are separated by an aluminum oxide film and filled with an electrolyte solution. The electrodes are made from aluminum foil with an oxide film, and two winding leads are soldered onto the electrodes. When a voltage is applied to the electrodes, a current will flow, and this current will cause the polarization of the oxide film.

The polarization of the oxide film changes the electric field, which leads to a capacitance. The amount of capacitance depends on the thickness of the oxide film and the surface area of the electrodes. The electrolyte also affects the capacitance as it increases the dielectric constant of the capacitor.

Conclusion

The MAL210618332E3 aluminum electrolytic capacitor is a widely used device and offers many advantages such as high capacitance values, reliable operation, and long life. It is typically used in power supply and energy storage circuits as it is capable of providing large amounts of energy storage and power filtering. The working principle of the MAL210618332E3 capacitors is based on the polarization of an oxide film which results in a capacitance based on the thickness of the oxide film and the surface area of the electrodes.
