Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are electrical components made of two conductors separated by an electrolyte. These conductors and electrolyte act as a storage device, and are capable of storing and releasing electrical energy. These capacitors work by taking advantage of the fact that when two metallic conductors are immersed in an electrolyte solution, a current flows between the two conductors.

The B43601E2228M000 aluminum electrolytic capacitor is a polarized capacitor characterized by a high capacitance density and low leakage current. It is available in case sizes E12, E19, or E39 and is capable of operating at a temperature of -55 to +85°C.

In terms of its application fields, this capacitor is typically used in high-frequency filters, telecom systems, audio amplifiers, and power supply circuits. It can also be used in automotive, consumer electronics, and other industrial applications.

Working Principle

The working principle of an aluminum electrolytic capacitor is based on the “capacitance effect”, a property of electricity that stores a charge on one of two metallic conductors separated by an electrolyte solution. This is known as a parallel-plate capacitor, and is the most common type of capacitor.

The two metallic electrodes are generally made from aluminum foil. Each electrode is bent to form a cylinder around the electrolyte solution and has a thin oxide layer on its outer surface. This oxide layer acts like a barrier, disrupting the flow of electrons and preventing the current from flowing between the two conductors.

When voltage is applied across the capacitor, the oxide layer changes its structure to allow current to flow through it. When the voltage is removed, the oxide layer reforms and returns to its original state, preventing electrons from flowing through.

This mechanism allows the capacitor to store a certain amount of charge, and release the charge when voltage is applied across it. This is the basic working principle of an aluminum electrolytic capacitor such as the B43601E2228M000.
