Aluminum electrolytic capacitors are commonly used components in electric circuits. They are so called because the component and the capacitor characteristics depends on the electrolyte in which it is immersed. The UUA1A221MNL1GS capacitor belongs to this kind of capacitors. In this article, we’ll take a look at the application field and working principle of the UUA1A221MNL1GS capacitors.

Application Field of UUA1A221MNL1GS

The UUA1A221MNL1GS capcitor is a high-capacity aluminum electrolytic capacitor with an electrolyte of ethylene glycol and propylene carbonate. It has an operating temperature range of -25 to 85°C and a lifespan of more than 2000 hours. Furthermore, it has an extremely long service life, even in extreme conditions. Therefore, UUA1A221MNL1GS capacitors can be used quite extensively in applications such as AC power supply, power filter, buzzer, precision measurement equipment, digital LCD power supply, frequency converter, and so on.

Working Principle of UUA1A221MNL1GS

UUA1A221MNL1GS capacitors are constructed using a thin layer of aluminum as the anode, a thin layer of aluminum oxide as the dielectric, and a liquid electrolyte as the cathode. The electrolyte acts as a proton conductor, while the oxide layer acts as an electrical insulator. The oxidation reaction of aluminum during the formation of aluminum oxide creates an electric field that enables the capacitor to store energy. This electric field exists between the two metal layers and is sustained by the electrolyte.

In operation, voltage is applied to the capacitor, which causes a current to flow from the anode to the cathode through the electrolyte. This current causes ions to migrate through the electrolytic solution, creating an electrostatic field that stores energy in the dielectric medium between the two electrodes. When the current is removed, the stored electrostatic field remains intact, and the capacitor can be discharged to produce the same amount of energy that was stored earlier.

The UUA1A221MNL1GS capacitor is designed with a thinner oxide layer for better energy storage and a higher operational temperature range for more extreme applications. This capacitor is highly reliable and offers good leakage current characteristics even at high frequencies, making it ideal for applications such as power supplies, AC filter circuits, and precision measurement equipment.

Conclusion

The UUA1A221MNL1GS aluminum electrolytic capacitor offers a high capacity and good leakage current characteristics even at high frequencies, making it suitable for various applications from AC power supply to frequency converters. It is also designed with a thinner oxide layer for better energy storage and a higher operational temperature range for more extreme applications. With its reliability and long service life, the UUA1A221MNL1GS capacitor is an excellent choice for electric circuits.
