Working Principle

B43866A4226M aluminum electrolytic capacitors are based on electrolytic capacitor technology, which uses an electrolyte as an insulator between a pair of metal plates. When these two metal plates are connected to an external electrical circuit, the capacitance, energy storage and frequency response of the capacitor are changed.

The main components of an electrolytic capacitor are anode foil, cathode foil, and electrolyte. The anode foil is made from aluminum foil with an oxide (Al2O3) coating. The coated aluminum foil increases the surface area and capacitance. The cathode foil is made from a different material, such as zinc, copper, cobalt, or nickel. The electrolyte is a liquid or gel material, such as an acid, glycol, or a mixture of both.

When the capacitor is connected to an external circuit, the molecules of the electrolyte react with the metal layers on the anode and cathode foils. This forms an oxide layer on the anode foil, which acts as an insulation layer. The oxide layer allows current to only flow in one direction. This direction is determined by the external circuit.

The capacitance of the aluminum electrolytic capacitor is determined by its surface area, oxide layer thickness, insulation layer insulation resistance, and the distance between the anode and cathode foils. The insulation layer also helps to reduce leakage current and dielectric absorption.

B43866A4226M aluminum electrolytic capacitors are designed with an improved robustness and high frequency response. They feature a high ripple current capacity and low equivalent series resistance which contributes to the overall performance of the capacitor.
