Introduction to Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors, also known as electrolytic capacitors, are typically the most commonly used passive components. These capacitors are made from an aluminum oxide film as an insulating material and aluminum foil as the other terminal of the capacitor. Due to its flat surface geometry, its electrical and mechanical properties are close to those of the ideal capacitor. Aluminum electrolytic capacitors have very low electrical losses and are composed of positive and negative electrodes with a dielectric oxide layer, which makes them highly reliable and capable of withstanding high voltages and temperatures.

Their Application Fields and Working Principle

Aluminum electrolytic capacitors are used in many different application fields such as power supplies, automotive electronics, communications and consumer electronics. Aluminium electrolytic capacitors are mostly polarized capacitors that rely on the oxide layer formed on the surfaces of electrode foils to function as the dielectric material to generate a charge. When a voltage difference is applied between the terminals, a current is drawn, and a charge is generated. This displacement charge generates an electric fieldcentred between the anode and the cathode, and forms the dielectric layer. The stored charge increases the capacity of the capacitor.
