Aluminium Electrolytic Capacitors

The 381LQ823M010A452 is an aluminium electrolytic capacitor.

Application Field

Aluminium electrolytic capacitors are widely-used components in circuits that require large capacitance such as power supplies, motor drives and inverters. They are also used as smoothing and stabilizing components, for decoupling circuits or for providing charge storage.

The 381LQ823M010A452 is suitable for high voltage applications and has a working voltage of 450V. Its advantages include being insulated, robust, low cost, and able to provide high capacitance values.

Working Principle

Aluminium electrolytic capacitors consist of two metal plates which are separated by an electrolyte. Between the plates, oxide films are formed by anodizing the aluminium. These films act as a dielectric, allowing electric charges to accumulate and polarize the plates, resulting in a capacitance. The capacity of the capacitor changes when the applied voltage increases, the anodizing films become thicker and the capacitance increases. At high voltage, the anodizing films become thinner again and the capacitance decreases.

The 381LQ823M010A452 also has an adjustable capacitance, which can be adjusted by changing the anode voltage. This allows the capacitor to adapt to the changing voltage requirements of an application.

Conclusion

The 381LQ823M010A452 is an aluminium electrolytic capacitor that is ideal for high voltage applications, and is suitable for use in power supplies, motor drives and inverters. Its high capacitance and adjustable capacitance make it a valuable component in any circuit.
