Aluminum Electrolytic Capacitors: B41231B4479M000 Application Field and Working Principle

Aluminum electrolytic capacitors are widely used in power supply systems and are essential components of many electronic devices. When assembled in a circuit, they can store electrical energy, charge and discharge, and produce an electric field effect. They are commonly used in electronic circuits to filter and decouple certain high-frequency currents. B41231B4479M000 is an aluminum electrolytic capacitor produced by Schottky Corporation, which uses stabilized tantalum foil as the anode and oxygen-free copper foil as the cathode.

Application Field

B41231B4479M000 has the characteristics of excellent performance, large capacity, small volume, high reliability, long life, and wide temperature range. It is widely used in the fields of electronic equipment and communication technology. It can also be used in various electronic devices, such as powering and protecting circuit devices, adjusting signals, eliminating electromagnetic interference (EMI), and capacitive energy storage. It is also suitable for use in aging tests and life tests of electronic products.

Working Principle

The operating principle of aluminum electrolytic capacitors is the electric double layer effect. This effect forms a static electric field at the interface between the electrode and the electrolyte. This static electric field influences the behavior of charge carriers in the electrolyte and is beneficial for the stability of the electric double layer. The anode and cathode of the B41231B4479M000 are made of stabilized tantalum foil and oxygen-free copper foil, respectively. Between the anode and the cathode, there is a thin layer of electrolyte, in which positive and negative ions are arranged in layers. When a potential difference is applied to the two electrodes, positive ions on the anode will be attracted to the cathode, while negative ions on the cathode will be pushed away from the anode. This movement of ions generates a charge that is accumulated in the electrolyte layer, thus forming a capacitor.

Conclusion

Aluminum electrolytic capacitor B41231B4479M000 produced by Schottky Corporation is suitable for wide temperature range, high reliability, and long life. It can be widely used in many fields of electronic equipment and communication technology. Its operating principle is based on the electric double layer effect, which forms a static electric field at the interface between the anode and the electrolyte.
