Aluminum Electrolytic Capacitors

861021483005 application field and working principle

Aluminum Electrolytic Capacitors, also known as electrolytic capacitors, are polarized capacitors. They offer the highest capacitance values in the most compact case sizes. As they are based on aluminum electrolyte system, they are used in all areas of electronics, and they are especially suitable for various applications in power electronics.

The working principle of aluminium electrolytic capacitors is based on the process of oxide layer formation on aluminium metal. During assembly process, a thin oxide layer is formed by passing a controlled electrical current through an electrolyte-soaked anode. This oxide layer acts as an insulating barrier between the anode and the electrolyte, enabling field-induced polarization and thus creating a very high capacitance value.

The application fields of 861021483005 mainly include automotive, healthcare, lighting, renewable energy, power train, electronics, and so on. The most popular use of it can be found in electric vehicles, where it helps to control power distribution and energy flow. It acts as a buffer to minimize energy fluctuations and reduce mechanical vibrations in power trains. In addition, it can be used in the medical industry for monitoring vital parameters during surgical operations.

As for its working principle, an electric field builds up between two metal plate electrodes when a voltage is applied. This electric field causes a polarization of the dielectric material (the insulator between electrodes) resulting in the stored charge and the stored energy. The stored charge is proportional to the capacitance, which is measured in Farads (1 Farad is equal to 1 coulomb per volt). The electric field also affects the oxide layer on the metal electrodes, thus increasing the overall capacitance.

In summary, 861021483005 is part of the aluminum electrolytic capacitor family, which are widely used in various electronic applications, such as automotive, healthcare, and renewable energy. Its working principle is based on the process of oxide layer formation on metal electrodes, resulting in high capacitance value stored in the polarized dielectric material. Furthermore, it can also be used to regulate energy fluctuations and reduce mechanical vibrations in power trains.
