Aluminium electrolytic capacitors are a type of electrical component known for their ability to store and release energy. In this article, we take a look at the CGS133U040V4C model of such capacitors to discover its various application fields and working principles.

Description

CGS133U040V4C is a series of aluminium electrolytic capacitors, produced by the Chinese corporation Yageo. It is classified as a miniature radial leaded type of capacitor, with rated voltages of between 6.3V and 63V and working temperature ranges between -40°C and 85°C. CGS133U040V4C capacitors also possess axial leaded versions tagged with \'L\', and maximum capacitance values of between 2.2μF and 470μF. In general, these types of capacitors have an operating life of about 2000 hours under a rated temperature of 85°C.

Working Principle

The working principle of aluminium electrolytic capacitors is derived from the fact that it consists of two electrodes, an anode and a cathode, which are separated by an electrolyte material. The anode and electrolyte form a porous oxide film that acts as the dielectric material in the capacitor. This dielectric material helps store electrical energy in the form of electrical fields between the two metallic plates. When the positively charged anode is connected to the positive voltage supply, electrons start to flow from the anode towards the cathode, creating an electrostatic field between the two. A potential difference is thus established between the two plates, allowing for charge to accumulate at the cathode, creating capacitance.

Applications

The CGS133U040V4C range of aluminium electrolytic capacitors have found wide application in microphones, speakers, radios, tuning amplifiers, hearing aids, audio equipment, scanners, power supplies, and motors, which require a capacitance between 2.2μF and 470μF. Apart from these, due to their polarized nature, they are also widely used in DC to AC converters and other related circuits.

Due to their small size and low cost, they are also used for applications such as decoupling circuits in laptops and PCB boards, high frequency snubber circuits, high ripple current and power factor correction circuits, pulse and audio circuit applications, anti-noise circuits in televisions, as well as many consumer electronics.

Conclusion

The CGS133U040V4C range from Yageo serves as an example of the increasing importance of aluminium electrolytic capacitors today. With their wide working temperature range from -40°C to 85°C, their rated voltage range of 6.3V to 63V, as well as their maximum capacitance of between 2.2μF to 470μF, these types of capacitors have found multiple application fields in various electronics circuits. And since they are both low-priced and compact, they can be used to create many different products and small-scale applications.
