Aluminum Electrolytic Capacitors

An aluminum electrolytic capacitor, also known as an Al-electrolytic or an electrolytic aluminum capacitor, is a polarised capacitor which uses an electrolyte to achieve a larger capacitance than other types of capacitors. This type of capacitor is often used in engine controllers, digital systems, UPSs, audio equipment, and telecommunication systems. The construction of this type of capacitor is an anode made from aluminum foil, a dielectric layer of oxidized aluminum, and a cathode along with its electrolyte.

Working Principle

Aluminum electrolytic capacitors use an anode and electrolyte combination to increase capacitance. The anode is made from aluminum foil and is coated with an oxide layer. The oxide layer acts as the dielectric between the anode and the cathode. The electrolyte is the electric conductor between the anode and the cathode, which is formed by the liquid electrolyte applied to the both side surfaces of the capacitor. During operation, electrical current is exchanged between the anode and the cathode via the electrolyte and this increases the capacitance of the capacitor.

The LPX121M400C1P3 aluminum electrolytic capacitor has a high capacitance and low ESR, which makes it suitable for a variety of power conversion systems. Its low-profile design makes it suitable for limited space and height applications, while its long-life characteristics make it ideal for power supplies and LCD backlight inverters.
