Introduction to Aluminum Electrolytic Capacitors

An Aluminum Electrolytic Capacitor, or simply suitably called an "electrolytic" is a polarized capacitor that uses a metal oxide film as a dielectric material. It has the highest capacitance per unit volume compared to other types of capacitors. Electrolytic capacitors are mainly used for high-frequency decoupling, energy storage and pulse rectification.

200MXG390MEFC20X30 Application Field and Working Principle

The 200MXG390MEFC20X30 capacitor is a non-solid, non-metallic double-layer aluminum electrolytic capacitor. It is classified as a high-temperature, high-voltage capacitor. This kind of capacitor is typically used in DC-DC converters, battery backups, common mode filtering, and automotive components.The capacitor works by creating a static electric field between two conductors. This electric field holds two layers of oxide film against two pieces of metal, the first being a positively charged anode, and the second being a negatively charged cathode. These two electrodes are then connected to the terminals of the capacitor to form an electrical circuit.As the current flows through the capacitor, the anode of the capacitor is polarized, and the oxide film begins to form a layer between the two metal plates. This layer creates a very high capacitance. In a 200MXG390MEFC20X30 aluminum electrolytic capacitor, the dielectric material of the oxide film is formed by a double-layer of aluminum oxide which facilitates the capacitor’s high-temperature operation. The oxide layer also results in a higher capacitance per unit volume.The 200MXG390MEFC20X30 capacitor also features a special caged construction to help protect the internal electrodes and dielectric. This design also helps the capacitor to operate at a higher temperature than other aluminum electrolytic capacitors. Additionally, its design provides high mechanical stability, which makes the capacitor more robust and reliable.

Conclusion

The 200MXG390MEFC20X30 is an aluminum electrolytic capacitor that is designed for high-temperature and high-voltage applications. It features a double layer of aluminum oxide for high capacitance and a caged design for protection and mechanical stability. This makes it an ideal choice for applications such as DC-DC converters, battery backups, common mode filtering, and automotive components.
