Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are widely used in electronic industry due to their low cost, high capacitance and long-term reliability. The UVP0J222MHD is an aluminum electrocapacitor developed by the industrial manufacturer Delphi. Its application field and working principle will be discussed in this article.

Introduction

Aluminum electrolytic capacitors are composed of two aluminum foils that are separated by a porous material called separator. On one side of the separator is an electrolyte, which provides a charge and also serves as a current conduction path. The other two sides of the separator are covered with aluminum oxide, which acts as an insulator and prevents the two metal foils from coming into contact with one another.UVP0J222MHD is an aluminum electrolytic capacitor with a rated voltage of 16VDC and a capacitance of 22µF. It has a maximum operating temperature of 105oC. Its main advantages are low cost and low ESR (equivalent series resistance).

Application Field

The UVP0J222MHD is mainly used for filtering and decoupling in power supplies, as well as in automotive and industrial applications. It is also used for snubbing applications. In a power supply, it helps filter out high frequency noise, ensuring clean and accurate power. It is also used in automotive applications to reduce switching transients in low voltage circuits. In industrial applications, it can also reduce failure rates of digital circuits due to the filtering of high frequency noise.

Working Principle

The working principle of an aluminum electrolytic capacitor is based on the principle of electrostatic attraction. When a voltage is applied to the two aluminum foils, an electrostatic attraction is created between them. This attraction causes a redistribution of the electric charges in the electrolyte, eventually creating an electric double layer between the two foils. The electric double layer enables the capacitor to store energy and establish a current flow. In the UVP0J222MHD, the aluminum oxide layer acts as an insulator, preventing any electric contact between the two foils. Therefore, the capacitor can store a large amount of energy, even at high temperatures.

Conclusion

In conclusion, the UVP0J222MHD is an aluminum electrolytic capacitor with a rated voltage of 16 VDC and a capacitance of 22µF. It is mainly used for filtering and decoupling in power supplies, in automotive applications, and in industrial applications. Its working principle is based on electrostatic attraction. The aluminum oxide layer acts as an insulator, preventing any electric contact between the two foils, allowing the capacitor to store energy and establish a current flow.
