Aluminum electrolytic capacitors are widely used in all kinds of devices thanks to their numerous advantages. Among them, UPJ1K820MPD is one of the most popular models. With a long duration and excellent capability of maintaining performance throughout its life cycle, UPJ1K820MPD stands out from the rest of aluminum electrolytic capacitors.

UPJ1K820MPD Application Field

Encompassing a broad variety of fields, UPJ1K820MPD’s application is particularly noteworthy in the power supplies, motors and automotive fields. With its high load, low self-inductance and excellent insulation accuracy, UPJ1K820MPD is often used in power supplies. It helps reduce the size of the transformer and filter circuit, and optimize the circuit configuration in the design process. Besides, thanks to its reliability and low internal resistance, UPJ1K820MPD is used in the motor and automotive fields to regulate current and reduce power loss.

UPJ1K820MPD Working Principle

The essence of a capacitor is its ability to store electrical energy. Aluminum electrolytic capacitors have round cylindrical shapes with positive and negative terminals connected respectively to an electrolyte anode and a dielectric oxide layer on a rolled aluminum foil inside the cylinder. This oxide layer stores the charge and is polarized by the applied voltage. A separator made of non-woven material controls the electric current and maintains a uniform electric field. To suit different application requirements, this type of capacitor is also made with different sizes and shapes.

Conclusion

Aluminum electrolytic capacitors are popularly used in a wide range of fields thanks to their excellent capabilities of resource management and performance. Particularly, UPJ1K820MPD, as a leading model in the industry, possesses remarkable advantages in the power supply, motor and automotive fields. Its applications are based on the basic mechanism of the capacitor, the round cylindrical shape with positive and negative terminals connected to the anode and dielectric oxide layer respectively, as well as the separator made of non-woven material to control and maintain a uniform electric field. All these significant features make UPJ1K820MPD a popular choice for many applications.
