Aluminum Electrolytic Capacitors

AIuminum electrolytic capacitors assume a special position among the various types of capacitors since their principle of operation relies, in part, on electrochemical processes. The advantages of aluminum electrolytic capacitors that have led to their wide application range are their high volumetric efficiency (i.e. capacitance per unit volume), which enables the production of …

Aluminum electrolytic capacitor

OverviewBasic informationMaterialsProductionStylesHistoryElectrical parametersReliability, lifetime and failure modes

Aluminium electrolytic capacitors are (usually) polarized electrolytic capacitors whose anode electrode (+) is made of a pure aluminium foil with an etched surface. The aluminum forms a very thin insulating layer of aluminium oxide by anodization that acts as the dielectric of the capacitor. A non-solid electrolyte covers the rough surface of the oxide layer, serving in principle as the second electrode (cathode) …

Technical Note

Aluminum, which is main material in an aluminum electrolytic capacitor, forms an oxide layer (Al2O 3) on its surface when the aluminum is set as anode and charged with electricity in elec-trolyte. The aluminum foil with an oxide layer formed thereon, as shown in Fig. 5, is capable of rectifying electriccurrent in elec-trolyte.
