Aluminum Electrolytic Capacitors

B43723A5129M050 capacitors are one kind of the aluminum electrolytic capacitors which have wide applications and varied working principles. In general, their function is to store, filter, and protect electric current, so they have become one of the key components used in a variety of electronic circuits.

As the name implies, the aluminum electrolytic capacitors are made of an aluminum oxide thin film deposited on an anodized aluminum plate. Because of the large surface area offered by the aluminum plate, it can store a large quantity of charge within a much smaller package size as compared to other types of capacitors. The anodizing process is the key reason for their high dielectric strength and their useful properties.

The aluminum electrolytic capacitors are polarized to ensure they correctly discharge their stored energy. Its electrodes could be either aluminum foil electrodes or plastic film electrodes. In this case, the B43723A5129M050 has the aluminum foil electrodes to offer more reliable performance.

The working principle of aluminum electrolytic capacitor is mainly split into two categories. Initially, it stores energy through a chemical double layer created when electric field passes through an electrolytic solution or electrolyte containing electric currents. This phenomenon is also known as the Faradaic effect and the stored energy can be represented as a change in the capacitance. Secondly, it stores electric energy in its dielectric film. When polarization happens in the dielectric because of electrostatic induction, electric charges will be stored.

On top of its dielectric film, the B43723A5129M050 also adds a variety of additives such as conductive ions, reducing agents, and lubricants to improve its aging performance and extend its operating life. With its long life span and reliable performance, it is frequently used in DC filters, power circuits, and equipment. It also has good frequency characteristics and ripple current capabilities.

The aluminum electrolytic capacitors are quite popular today, and cost relatively much cheaper than other types of capacitors. Besides, these capacitors offer a good combination of good performance and small size, they are the first choice for many electronic projects, including the B43723A5129M050.
