Aluminum Electrolytic Capacitors: CGO223M020L Application Field and Working Principle

Aluminum electrolytic capacitors are widely used in all kinds of circuits, and their application fields are versatile. Here, we will focus on the application field and working principle of the CGO223M020L aluminum electrolytic capacitor.

Application Field of CGO223M020L Aluminum Electrolytic Capacitor

CGO223M020L aluminum electrolytic capacitor is mainly used in LED dimming systems and power inverters, with a maximum ripple current of over 300 A and a wide working voltage ranging from -50 to +125 volts. It is also suitable for some circuit components which need low internal impedance requirement and highly reliable power supply. Due to its high ripple current and wide operating temperature range of -55℃ to +105℃, it is the ideal choice for high-power applications such as automotive lights, LED lights, solar inverters and wind turbines.

Working Principle of CGO223M020L Aluminum Electrolytic Capacitor

The CGO223M020L aluminum electrolytic capacitor is a kind of electrolytic capacitor which usually consists of anion and cation layers. It works by utilizing the difference in electric potentials between the two layers to form a dielectric. The anion layer is a charged electrode, composed of aluminum and its oxide film, while the cation layer is a charged electrode, composed of electrolyte. When an electric field is applied between the two electrodes, electrons will flow, forming a current. This current will cause a redistribution of charges, and the cation layer will act as an insulator, preventing further current flow.When an AC current is applied to an aluminum electrolytic capacitor, the capacitance is inversely proportional to the frequency of the applied current. This is because the oxide film on the anion layer has a low dielectric constant and cannot maintain a steady capacitance in high frequency AC circuits.To increase the capacitance, aluminum electrolytic capacitors have a unique design – an anode and a cathode lies inside the capacitor and surrounded by an electrolyte. This electrolyte, along with an anion layer and a cation layer, is used to form a stable dielectric with a higher capacitance.

Conclusion

CGO223M020L aluminum electrolytic capacitor is an ideal choice for a wide variety of applications due to its high ripple current and wide operating temperature range. Its working principle is based on the formation of a dielectric between the anion and cation layers in order to store electric energy. Its capacitance is inversely proportional to the frequency of the applied current, and it can increase the capacitance by using a special design.
