Aluminum electrolytic capacitors, also known as electrolytic capacitors, are polarized capacitors whose anode electrode is a metal oxide layer formed by electrolysis on the surface of an aluminum foil. The B43254C4107M is an aluminum electrolytic capacitor, so this article will discuss the application field and working principle of such a capacitor.

Aluminum electrolytic capacitors are mainly divided into two types: axial lead type and radial lead type, and their capacitance and voltage rating are particularly wide, ranging from a few micro-thou Farad capacitors to more than 1000uF high-voltage capacitors of several thousand volts. The B43254C4107M is a radial, snap-in, pre-assembled solid capacitor with a rated DC voltage of 10 V DC and is mainly used in communication base station equipment, especially for power supplies and signal filtering.

The working principle of aluminum electrolytic capacitors is that an oxide film formed by anodic oxidation on the surface of aluminum foil is used as the anode electrode to form a capacitor with the electrolyte used as the cathode electrode. The dielectric layer of this capacitor is an oxide film, which causes dielectric losses due to the presence of ions in the electrolyte, resulting in energy conversion and heat generation. Aluminum electrolytic capacitors also have a large equivalent series resistance (ESR), which acts as a resistance in the circuit.

In addition, aluminum electrolytic capacitors also have a certain self-healing effect, which means that when a large inrush current passes through the capacitor during the start-up of the equipment, the temperature of the capacitor increases due to Joule\'s heating, and the oxide film formed on the surface of the aluminum foil also increases melting, and some oxide film is removed, so that the insulation of the aluminum foil is improved and the current capacity increases. At the same time, some of the parts that are damaged in the reverse direction will be restored, enabling the capacitor to continue to work without being damaged.

In conclusion, aluminum electrolytic capacitors such as the B43254C4107M are widely used in communication base station equipment, especially for power supplies and signal filtering, and their working principle involves the formation of an oxide film-covered aluminum foil used as the anode, along with the electrolyte used as the cathode. They also have a large equivalent series resistance and a certain self-healing effect, making them a highly reliable component.
