It is also often used as a filter capacitor in compact and portable electronics and as a deep discharge or charge capacitor.

Working Principle

An aluminum electrolytic capacitor consists of two aluminum plates and a dielectric layer between them. The aluminum plates are coated with an oxide dielectric layer and connected to the two leads. The anode and cathode are electrolytically covered with a conformal deposit that acts as a dielectric material to create a capacitance effect.When current is applied to the plates, a charge is stored in the capacitor. As a result, a voltage will be created between the plates. This is referred to as a capacitance effect and is the basic principle of operation for the UPJ1V221MPD.The UPJ1V221MPD is designed to be low-cost and has a low ESR (equivalent series resistance). It also has a high ripple current and can store large amounts of energy. As such, it is well suited for applications with high current and voltage requirements.

Conclusion

The UPJ1V221MPD is a bipolar aluminum electrolytic capacitor that features a low resistance and long life and is perfect for applications with high current and voltage requirements. It is typically used in power supply systems, high-end audio equipment and other similar applications. The UPJ1V221MPD is also suitable for high frequency and high voltage applications, such as high frequency rectifiers, inverters, and power converters. Its operation is based on the basic theory of capacitance and the principle of applied current creating a voltage between the two terminals.
