UPJ0J222MPD working principle

The UPJ0J222MPD is an aluminum electrolytic capacitor, which has an anode and a cathode separated by an electrolyte. The anode is a thin aluminum foil with an oxide layer, while the cathode is an aluminum, zinc, or steel slug. The electrolyte is a gel containing primarily boric acid and other acids.

When the capacitor is under AC voltage, chemical reactions will occur between the electrolytes and the aluminum foil. This leads to the formation of a dielectric layer which is a thin insulating film that separates the anode and cathode. The thickness of this dielectric layer represents the capacitance value, and can vary depending on the amount of current passing through it.

Once the voltage is removed, the dielectric layer is reformed. This signifies that the capacitor is able to be used repeatedly. Since this type of capacitor offers a high capacitance value, it is suitable for large capacitative loads.

Conclusion

The UPJ0J222MPD is a popular model of aluminum electrolytic capacitor which is suitable for many applications. It offers excellent temperature endurance and leakage current, as well as high frequency operation. It can be used in automotive, computer systems, communication, and other electronic devices. The working principle involves the formation of a thin dielectric layer which acts as an insulator between the anode and cathode. With its wide range of capacitance values, it is suitable for large capacitive loads.
