Aluminum Electrolytic Capacitors - LQR2G392MSEGBN Application Field and Working Principle

Aluminum electrolytic capacitors (AECs) are a type of specialized capacitor commonly used in numerous electrical and electronic applications such as filter circuits, audio crossover networks, power supplies, etc. One such AEC type is the LQR2G392MSEGBN which is a surface mount, low profile, long life, non-polarized aluminum electrolytic capacitor.

Application Field

The LQR2G392MSEGBN aluminum electrolytic capacitor is widely used in power supplies, energy storage systems, and various other electronic devices. Specifically in power supplies, AECs can be used for filtering and for energy storage due to their ability to hold a large amount of charge in a relatively small package. The LQR2G392MSEGBN AEC is also suitable for the high frequency and low impedance applications common in audio crossover networks. Additionally, these devices are available in a variety of shapes and sizes, making them suitable for a variety of space-limited applications.

Working Principle

The \'heart\' of the LQR2G392MSEGBN aluminum electrolytic capacitor is an anode composed of aluminum foil containing etched nodules for increased surface area and impregnated with an electrolytic solution. The cathode is made of aluminum foil, also possessing etched nodules, and a paper/fabric separator to prevent short-circuiting.When a voltage is applied to the anode and cathode of the capacitor, charges begin to accumulate on the surfaces of each, and a dielectric layer formed between the anode and cathode greatly increases the capacitance of the AEC. The LQR2G392MSEGBN provides a long life due to an impregnated electrolytic solution which serves to pre-charge and refresh the capacitor, allowing it to maintain a consistent capacitance value with minimal losses over a much longer period of time than conventional polarized capacitors.

Conclusion

The LQR2G392MSEGBN is a versatile AEC that is suitable for a number of applications. Its low profile, long life, and non-polarized nature make it an ideal choice for applications that require a dependable and long-lasting capacitor. As such, the LQR2G392MSEGBN aluminum electrolytic capacitor is an excellent option for both commercial and industrial applications.
