Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are types of capacitors that use aluminum foil and a chemical electrolyte to achieve their function. They are widely used in both AC and DC circuits due to their high capacitance-to-volume ratio, low ESR and long life expectancy. Aluminum electrolytic capacitors are available in a variety of sizes and ratings, such as the B43305F2188M80 and B43305F2188M80.

Application Field

The B43305F2188M80 Aluminum Electrolytic Capacitor is a high-reliability, ultra-long life component. It is designed for applications in measure systems, power supplies, and input/output interfaces. It is widely used in various electronic circuits, such as medical equipment, military systems, industrial automations, motor drives, power supplies, and communication systems. It is also suitable for high temperature environments.

Working Principle

An aluminum electrolytic capacitor consists of two aluminum foil plates separated by an electrolyte. The plates are polarized via an anode and a cathode. The anode side is formed of an etched aluminum foil layer and an electrolyte solution, and the cathode side is formed of a synthetic rubber separator. When a voltage is applied, the electric field between the two plates induces a current, which forms a layer of metal oxide on the anode’s surface. This layer of metal oxide acts as a dielectric, thus forming a capacitor. The capacitance of the resulting capacitor depends on the thickness of the metal oxide layer, the area of the aluminum plates, and the relative permittivity of the electrolyte.

The capacitance of aluminum electrolytic capacitors can be relatively high, typically in the range of 25µF to 10,000 µF. They also have a low ESR (Equivalent Series Resistance) and can withstand higher voltages than other types of capacitors. Moreover, due to their relatively long life expectancy, aluminum electrolytic capacitors are ideal for use in long-term applications in which capacitance stability is required.
