400SXW10MEFC12.5X20

Aluminum Electrolytic Capacitors

The 400SXW10MEFC12.5X20 is an aluminum electrolytic capacitor. It is an electrical component popularly used in many electronic circuits. This type of capacitor is made up of two aluminum foils separated by paper saturated with an electrolyte. The foils are then rolled to form a cylindrical shape, which allows the capacitor to store a large amount of electrical charge.

Application Field

Aluminum electrolytic capacitors are used in a wide range of applications, such as power supplies, motor drives, energy storage, signal processors, and sound equipment. They are also used to filter alternating currents, adjust frequency response, and reduce electrical noise.

Working Principle

The major operating principle of an aluminum electrolytic capacitor is the ability of the two aluminum foils, separated by the dielectric electrolyte, to store electrical charge in the form of static charge. When an electric current flows through the capacitor, electrons move from the anode to the cathode, charging the capacitor. This stored energy then provides a charge to any electrical circuit connected to the capacitor. The dielectric electrolyte helps in preventing a short circuit between the foils, allowing the capacitor to store the charge without discharging until the external circuit needs it.

The capacitance of an aluminum electrolytic capacitor is determined by the amount of electrical charge it can store, which is measured in Farads. The Farad is a unit of capacitance. The higher the capacitance, the more charge the capacitor can store.

Conclusion

The 400SXW10MEFC12.5X20 is an aluminum electrolytic capacitor. It is commonly used in many electronic applications as an electrical filter to adjust frequency response, reduce electrical noise, and store electrical charge. It is characterized by its ability to store a large amount of charge, as measured in Farads.
