Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are widely used in various types of electronic equipment due to their widevoltage and high capacitance range, light weight, compact size and low cost. They are widely used in applications which require low ESR, high ripple current rating, low DF and long life, such as AC adapters, high frequency switch-mode power supplies, etc.The 520C202M450CC2B aluminum electrolytic capacitor belongs to the radial type aluminum electrolytic capacitor. Its capacitance is 2.2μF and its allowed voltage is 450V, which is mainly suitable for high frequency switches, DC to DC converters, DC motors, AC power supplies or voltage surge protection circuits.

Application fields of the 520C202M450CC2B aluminum electrolytic capacitor:

1. AC power frequency converting circuit, AC general filtering circuit, DC motor running speed controlling circuit, position controlling circuit, pulse-width modulation circuit, stepper motor starting and running speed controlling circuit, etc. 2. Voltage surge protection circuits, such as overvoltage, overcurrent, phase loss, etc. in various AC power systems. 3. Automobile, electric motorcycle, washing machines, video products, air conditioners, refrigerators, computers, microcontroller, etc.

Working principle of the 520C202M450CC2B aluminum electrolytic capacitor:

The working principle of the 520C202M450CC2B aluminum electrolytic capacitor is based on the phenomenon of dielectric polarization. In an electrolyte, an Anode and a Cathode are connected by two pieces of an Aluminum foil with a thin layer of dielectric oxide film. The dielectric oxide film is formed by electrolyzing the Anode and Cathode connection and the electrolytic chemical reaction. When a voltage is applied between the two electrodes, an electric field is applied to the dielectric oxide film, and the electrons are then polarized so that the dielectric oxide film increases its resistance to current flow. Generally speaking, the 520C202M450CC2B aluminum electrolytic capacitor comprises a spiral shape Aluminum foil as a pair of Anode and Cathode, a Gas Barrier Foil to separate the two from each other, and an electrolyte filling solution to lube the Aluminum foil and act as an electrolyte for the chemical reaction. During the operation process, when a voltage is applied between the Anode and Cathode, energy is stored in the dielectric oxide film. When the voltage is discharged along the electrode, energy is returned back to the outside. With the continuous discharging and charging, the capacity is built up in the aluminum electrolytic capacitor.

Conclusion

520C202M450CC2B aluminum electrolytic capacitor is mainly used for high frequency switch, DC to DC converters, DC motors, AC power supplies, voltage surge protection circuits, etc. For its capacitance is 2.2 μF and its allowed voltage is 450V. Its working principle is based on the dielectric polarization when applied with voltage between Anode and Cathode, and with energy stored and returned back depending on the volume of the voltage through the discharging and charging process.
