Application field of B41231C478M aluminum electrolytic capacitors

Aluminum electrolytic capacitors are widely used in various kinds of electronic equipment, audio equipment, as well as household appliances and other electrical and electronic products. B41231C478M aluminum electrolytic capacitors can be used in various audio power amplifiers, television power amplifiers, audio filter circuits and so on. Generally, B41231C478M aluminum electrolytic capacitors are applied in input-output DC blocking, energy storage, pulse decoupling, AC and DC filter circuits and coupling application.

Working principle of B41231C478M aluminum electrolytic capacitor

The working principle of B41231C478M aluminum electrolytic capacitor is based on the principle of electrolytic double-layer capacitor. It has two electrodes, one of which is made of aluminum foil. Its surface is sprayed with oxide film, which serves as the anode. The other electrodes are made of non-metallic materials, which act as the cathode. The two electrodes are connected through electrolyte, and the capacitor is formed by the electrochemical reaction.

At applied voltage, electrical charges accumulate on both sides of the oxide film and are stored in the electric double-layer of the capacitor. The dielectric of the capacitor is basically an oxide film formed by chemical treatment on the surface of the aluminum foil. When the voltage is applied, the oxide film will form an insulator, which forms a basic dielectric for storage. This storage process does not require energy from the outside, only the voltage applied on the capacitor.

Conclusion

B41231C478M aluminum electrolytic capacitors have a wide range of applications in modern electronic products, and their working principle is based on the principle of electrolytic double-layer capacitor. At applied voltage, electrical charges accumulate on both sides of the oxide film and are stored in the electric double-layer of the capacitor. This way, B41231C478M aluminum electrolytic capacitors provide a reliable storage device for a wide range of electronic applications.
