Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are devices which have a very high capacity for storing electrical energy and are generally composed of two aluminum foils with oxide layers formed on the elements. These capacitors are also known as electrolytic capacitors, aluminum electrolytic capacitors, or simply electrolysers. The abbreviation ‘ALS’ stands for Advanced Liquid System, which are caps designed to provide high energy capacity and low ESR at a reasonable price. The ALS80A561DB400 is a relatively large electrolytic capacitor, used in power, industrial, and medical systems.

Application Field

The ALS80A561DB400 is most commonly used in applications requiring high current, such as power Factor Correction (PFC) or soft start circuits, and is especially suited for DC-DC converters and AC-DC power supplies. Additionally, since the capacitor has a wide temperature range, it can be used in a wide variety of outdoor and indoor applications. It is also suitable for electromagnetic interference suppression and energy storage.

Working Principle

The ALS80A561DB400 is an aluminum electrolytic capacitor, which means it consists of two aluminum foils that are parallel to each other and separated by an oxide layer. The oxide layer acts as an insulator and stores electric charge, while one of the aluminum foils serves as a cathode and the other as an anode. Electric current is then passed between the two through the oxide layer, which causes the oxygen molecules to be adsorbed onto the surface of the cathode, which creates a charge imbalance between the anode and the cathode. This charge imbalance stores electric energy, while the aluminum foil acts as a dielectric.

Conclusion

The ALS80A561DB400 is a large aluminum electrolytic capacitor which has a wide temperature range, making it suitable for a variety of outdoor and indoor applications. It is primarily used in applications requiring high current such as PFC or soft start circuits and is particularly well suited for DC-DC converters and AC-DC power supplies. The working principle behind this capacitor is the formation of an oxide layer between two aluminum foils, which produces a charge imbalance for energy storage.
