Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are a type of capacitor that uses aluminium oxide as the dielectric. It is an important component for basic electronic parts. The main characteristics of aluminum electrolytic capacitor include large capacitance with small size, high voltage, low impedance, and small variety of form and size. Because of its good features, aluminum electrolytic capacitors have become the most widely used capacitors.

The working principle of an aluminum electrolytic capacitor is to use a polarized electrolyte to store negative charge on one of the plate and positive charge on the other plate and act as an insulator that can store energy. The electrolyte is a liquid or gel-like material that can conduct electricity and is located between two aluminum foil plates. One side of the electrolyte is a dielectric film made of aluminum oxide. This dielectric provides an insulating layer between the aluminum plates, and the strength of the electric field can be increased by adjusting the thickness of the dielectric layer. This increases the capacitance of the aluminum electrolytic capacitor.

When the capacitor is connected to a power source, current will flow through the electrolyte into the positive plate of the capacitor, resulting in an electrochemical reaction. This reaction forms an insulating layer of aluminum oxide along the edge of the positive plate. As more current is supplied, this layer thickens, further increasing the capacitor’s capacitance. The same is true for the negative plate of the capacitor, except that the insulating layer is formed by the electrolyte itself.

The aluminum electrolytic capacitor is also capable of handling extremely high amounts of current. This is due to the large surface area of the aluminum foils, as well as the thin dielectric layers that are able to handle high currents without breaking down. This makes them the ideal choice for high current applications such as motor control and power supplies.
