CGS682U025R2C application field and working principle

Aluminum electrolytic capacitors (also known as "wet electrolyte aluminum electrolytic capacitors") is one of the most widely used capacitor components because of its small size, high capacitance, long life and low price. Modern aluminum electrolytic capacitors widely used in consumer electronics and other industrial fields of direct current circuit, power supply and filter circuit, and also widely used in car power as well. CGS682U025R2C, as a typical member of aluminum electrolytic capacitors, is used in many applications and its working principle is as below.

As known to all, the aluminum electrolytic capacitor consists of a two electrodes separated by electrolyte, and the plates is made of pure aluminum foil which is subjected to anisotropic in direction. When electricity flows into the capacitor, the aluminum foil absorbs a layer of nonconductive "aluminum oxide film", which greatly increases the distance between the plates and acts as an insulator. Because the anodized aluminum oxide film thickness is usually only about 10 μm, it\'s very thin. In order to increase the plate spacing in aluminum electrolytic capacitors, a layer of porous Nonwoven fabric soaked by electrolyte electrolyte (electrolyte solid film) is used as separator in capacitor so as to increase the effective plate space of the capacitor. The CGS682U025R2C, which is a kind of aluminum electrolytic capacitor, is basically no different from other types.

The main application field of CGS682U025R2C is high frequency power electronics circuits, such as switching power supplies, UPS power supply, on-board chargers, medical power supplies and inverters. The capacitor can help perfect the filtering circuit of high frequency power electronics circuit, reduce the current and voltage peaks of the power supply, reduce the losses by current and voltage fluctuation and improve the power conversion efficiency of the circuit. Besides, CGS682U025R2C also has a wide range of uses in the field of audio power, such as better audio signal filtering, reduce power interference and protect the audio circuits.

In conclusion, CGS682U025R2C as a typical aluminum electrolytic capacitor is widely used in switching power supplies, UPS power supply, on-board chargers, medical power supplies and other power electronics and audio power fields. The key working principle of the capacitor is to increase the plate spacing of the capacitor by adding a layer of porous nonwoven fabric separator soaked with electrolyte, so as to improve the filtering effect of current and voltage of the power supply and protect the power electronics and audio circuits.
