Working Principle

The B41252A8128M000 capacitor works according to the same principle of operation as all aluminum electrolytic capacitors. It consists of two electrodes, in the form of aluminum foils, separated by a dielectric material in the form of a non-conductive aluminum oxide film. A chemical reaction between the electrolyte in which the capacitor is submerged and the aluminum foil electrodes forms the dielectric film. This dielectric film, along with the two aluminum foil electrodes, forms a capacitor, which is capable of storing electrical energy.

When an electrical field is applied to the capacitor, electrons flow through the dielectric. The electrons flow through the electrolyte, allowing them to flow through the capacitor. This set of electrons creates an electric field around the capacitor. This electric field creates an electrostatic charge on the capacitor, creating the storage of electrical energy.

Aluminum electrolytic capacitors like the B41252A8128M000 capacitor are also designed with space between the two aluminum foil electrodes. This called a ‘slotted aluminum foil’ design, and it is used to allow for maximum surface area between the two electrodes. The more surface area, the higher energy storage capacity of the capacitor. Therefore, the B41252A8128M000 capacitor is able to store much more electrical energy than other types of capacitors, making it ideal for applications in high-frequency and high-efficiency switching power supplies, circuit damping and glitch suppression.
