Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are widely used in power electronics, consumer electronics, and green energy due to their high energy density, robustness, long life, and affordability. In particular, B43644B2128M000 is a miniaturized aluminum electrolytic capacitor that offers optimal capacitance generation and exceptionally low loss in small size applications where space constraint is a major issue.

Application Field

B43644B2128M000 aluminum electrolytic capacitor is mainly used in precision power circuit design, like grid-connected photovoltaic energy conversion system, hybrid electric vehicle, computer peripherals and digital products, etc. Due to its superior performance, it can be used in various systems, such as voltage convertors, switching power supplies and motor drive circuits.

Working Principle

B43644B2128M000 aluminum electrolytic capacitors are built using advanced electrochemical technology. When voltage is applied across two metal plates suspended in an electrolyte solution, a thin anodic oxide layer forms on the surface of the plates. This layer acts as a barrier that prevents the metal plates from dissolving in the electrolyte solution while allowing them to stay in contact with the electrolyte to store electric charge. The thicker and denser the anodic oxide layer, the higher the capacitance and stability of the capacitor. Moreover, the capacitor is assembled with an epoxy board to protect it from direct contact with environmental elements, such as temperature and humidity. These aluminum electrolytic capacitors also provide high life expectancy due to their low resistance and self-healing feature. Low resistance implies high charge carrying capacity and energy storage capacity. Even if the charged particles are subjected to extreme pressure and a few of them break apart, the other particles will be able to balance out the damage and continue to work efficiently. Consequently, the life expectancy of aluminum electrolytic capacitors is extended.

Conclusion

B43644B2128M000 is an aluminum electrolytic capacitor which is mainly used in precision power circuit design. It offers superior performance with high energy density, robustness, and long life expectancy. It utilizes an advanced electrochemical technology to form a thin anodic oxide layer on the metal plates which acts as a barrier to prevent the metal plates from dissolving while allowing them to store electric charge. The capacitor is also assembled with an epoxy board to protect it from environmental elements, such as temperature and humidity. Thus, its application has been extended to a wide range of systems, such as voltage convertors, switching power supplies and motor drive circuits.
