Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are polarized electrolytic capacitors which are commonly used in power supplies, radio equipment, telephones, computers, automotive electronics, and other electronic circuits. The B43458A5129M000 is a non-solid aluminum electrolytic capacitor, providing a great combination of both high capacitance and high voltage rating in an industry standard 7.3 mm x 5.1 mm design.

Application Field

The B43458A5129M000 is primarily used for consumer electronic applications and telecommunications circuits. It is suitable for a wide range of applications due to its high capacitance and voltage rating. It is typically used as an input and output filter in switch mode power supplies, as well as to protect against voltage spikes in bridges, transient overvoltages, and power line switching. It can also be used to provide inrush current limiting, as well as to filter out electromagnetic interference in various types of electronic circuits.

Working Principle

The working principle of all types of aluminum electrolytic capacitors is essentially the same. It consists of two aluminum foil plates that are wound together with a separator between them. One of the foil plates is coated with a semiconductor electrolyte, and the other is coated with a porous material. This construction gives the capacitor its polarizing properties. When a voltage is applied to the capacitor, electrons begin to flow from one of the aluminum foils to the other. This creates an electric field between the two foils, which stores energy between the plates. As the voltage increases, the field strength increases, and the capacitance increases.

A reliable feature of this type of capacitor is its ability to maintain a stable voltage rating while under varying ambient temperature, pressure, and humidity conditions. This means that the device will operate in a wide range of environmental conditions, which allows it to be used in many different types of applications. Furthermore, aluminum electrolytic capacitors are very cost-effective, making them a popular choice for many circuit designs.
