Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are energy storage devices comprised of two aluminum foils separated by a thin layer of oxide film. A chemical reaction takes place between the aluminum foil and the electrolyte, resulting in a high capacitance polar electrolytic capacitor. The main application fields of EEE-FT1H221AP are in high-frequency, high-temperature, high-reliability and ultra-long-life applications.

Working Principle of Aluminum Electrolytic Capacitors

An aluminum electrolytic capacitor comprises two aluminum foils. One of them (the "positive" side) is covered with an oxide film, while the other (the "negative" side) is covered with an electrolyte. The capacitor works by using the oxide film on the positive side as a dielectric layer, separating the two aluminum plates in a capacitor. When a voltage is applied across the plates, a current will flow through the oxide film and create an electric field across the plates, the magnitude of which depends upon the capacitance, thus storing charge.

The oxide layer on each of the plates prevents current loss, preventing the capacitor from discharging, resulting in a long lifetime and high stability of the device. Since the surplus dielectric layer of the aluminum electrolytic capacitor is made up of metal oxide, it has a much higher dielectric strength than other types of capacitors. This results in improved fatigue characteristics, better performance, and superior reliability.
