Aluminum electrolytic capacitors are widely used across a variety of applications from filtering power supply ripple to providing input and output bypassing for RF sector applications. The UWT1C330MCR1GB is amongst the most popular aluminum electrolytic capacitors and is widely used in high voltage and high reliability applications. This article will look at the application field and discuss the working principle for the UWT1C330MCR1GB.

Application Field

The UWT1C330MCR1GB is an aluminum electrolytic capacitor suitable for high voltage and high reliability applications. The capacitor has a nominal capacitance of 330uF, rated working voltage of 350VDC and an operating temperature range of -40°C to +105°C. It has a rated leakage current of 0.5CV or 2MA whichever is greater at 120Hz and 25°C.Typically the UWT1C330MCR1GB would be used in applications where higher capacitance values are required. It is suitable for applications such as switching power supplies, converters, inverters, motor control, and other high-voltage applications that require higher reliability and longer lifetime.

Working Principle

The UWT1C330MCR1GB, like all aluminum electrolytic capacitors, works by the principle of electrolytic action. They consist of two metallic plates (an anode and a cathode), immersed in an Electrolyte between them. The two plates are separated by a piece of insulating paper. In this capacitor the electrolyte is a liquid which is high in ionic content formed by absorbing oxygen into water or glycol.When a potential is applied across the two plates, an electric current is created which causes oxygen ions to be attracted to one of the plates, creating a highly charged layer on the plate. This layer is called an ‘oxygenated layer’ which acts as an insulator and significantly increases the capacitance.The two plates not only act as a conductor but also act as a dielectric, thus allowing the capacitor to store electrical energy. The higher the potential applied across the plates, the thicker the oxygenated layer and the higher the capacitance.In addition to this, the UWT1C330MCR1GB has several unique design features that enable higher reliability and longer lifetime. The most important being the use of high-purity aluminum which reduces leakage current and improves insulation. The capacitor also uses a ‘plate-to-electrolyte’ construction which further improves the insulation and prevent the risk of short-circuiting.

Conclusion

The UWT1C330MCR1GB is a highly reliable aluminum electrolytic capacitor which is suitable for a wide range of high voltage applications. Its construction consists of two plates which are separated by a piece of insulating paper, immersed in an electrolyte between them. When a potential is applied across the two plates, an electric current is created which causes an oxygenated layer to form on one of the plates, significantly increasing its capacitance. This capacitor also has several unique design features which make it highly reliable and able to provide longer life.
