Aluminum Electrolytic Capacitors

An aluminum electrolytic capacitor is an electrical component that stores energy using an aluminum foil as an anode, a dielectric layer, and a liquid electrolyte as a cathode. This type of capacitor is ideal for applications that require large amounts of energy storage due to their ability to hold large amounts of charge and their low ESR (equivalent series resistance).

B41890A5128M Application Field and Working Principle

The B41890A5128M is a 13,500uF, 125VDC aluminum electrolytic capacitor that can be used in a wide variety of applications. It is ideal for use in high-temperature environments, such as automotive under-the-hood applications, with its operating temperature range of -55ºC to +105ºC. It also has a high ripple current capability of 122mA and a high ripple voltage capability of 15VDC.

The working principle of an aluminum electrolytic capacitor is that it stores energy by using an anode of aluminum foil as the surface that the energy is absorbed, followed by a dielectric layer, then a liquid electrolyte as the cathode. The anode accepts the current, the dielectric layer provides insulation between the anode and cathode, and the electrolyte acts as the electrical medium. As current flows through the capacitor, an electric charge is stored on the anode and the electrolyte creates the electrical circuit. This charge enables the capacitor to store energy for later use.

The B41890A5128M aluminum electrolytic capacitor is capable of withstanding high levels of voltage and current surges due to its storage capabilities. Its low ESR allows for reduced heat generation, enabling the capacitor to dissipate heat more efficiently.
