As is the case with all capacitors, an aluminum electrolytic capacitor comprises two electrically con-ductive material layers that are separated by a dielectric layer. One electrode (the anode) is formed by an aluminum foil with an enlarged surface area. The oxide layer (Al2O3) that is built up on this is used as the dielectric.
Based on the formula of the plate capacitor, the specific capacitance of the aluminum electrolytic capacitors is mainly determined by the specific surface area of …
