Aluminum Electrolytic Capacitors

UMW0G331MDD1TP Application Field and Working Principle

Aluminum electrolytic capacitors, also known as “electrolytic capacitors”, are a type of capacitor which uses an electrolyte, typically an aqueous solution of sulfuric acid, as its medium instead of the mica, paper, or oil traditionally used in capacitors. The UMW0G331MDD1TP series is a type of radial-leaded, low-voltage aluminum electrolytic capacitors, which are commonly used in filtering and buffering of power line in various electronics such as computers, audio equipments, household appliances, and industrial control systems.

Working Principle

The working principle of theUMW0G331MDD1TPseries aluminum electrolytic capacitor is based on a physical phenomenon called “double-layer effect”. Specifically, when a voltage is applied between two metal plates immersed in an electrolyte, one of them would be charged positive while the other is negative. Then, on the surface of each plate negative and positive tiny charged particles will form opposite electrical charges, forming a double-layer capacitor. When current passes through this double-layer capacitor, a capacitance occurs and the capacitor works like a sponge to absorb this current.

Features

The UMW0G331MDD1TP series aluminum electrolytic capacitors are known for its excellent energy storage, low equivalent series resistance (ESR), and low own temperature rise. With features like very low impedance and high ripple current, UMW0G331MDD1TP series capacitors provide strong buffering and filtering to electronic devices. Another strength is its long life span which usually upwards of 10,000 hours, much longer than the 2,000 hour life-span of standard electrolytic capacitors.

Applications

The UMW0G331MDD1TP series aluminum electrolytic capacitors are widely used for power filtering, buffering, and compensation in analog and digital circuits. In computers, audio equipments, and household appliances, it can reduce DC power ripple and provide power high stability. Its low ESR and high surge capability make it an ideal component for DC-DC converters, photocopiers, medical equipments and many more.

Conclusion

In conclusion, the UMW0G331MDD1TP series aluminum electrolytic capacitors are a type of radial-leaded, low-voltage capacitors with excellent energy storage, low ESR, and high ripple current capabilities. With long life-span and strong buffering and filtering, they are commonly used in computers, audio equipments, household appliances, DC-DC converters, photocopiers and medical equipments, as well as many other analog and digital circuits.
