Introduction to Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are the most commonly used capacitors and have a wide variety of applications within electrical and electronic equipment. They are typically used as energy storage devices in order to supply current to an electronic circuit or device. The capacitance of a capacitor is determined by the size and construction of the capacitor and the material used for its construction.

Aluminum electrolytic capacitors are a type of polarized capacitor, which means the two plates are charged differently. This type of capacitor is used in situations where the energy stored needs to be quickly released, due to their quick response time. Aluminum electrolytic capacitors can also be used to filter out very high frequency noise generated by digital electronic devices.

These capacitors differ from traditional film capacitors in that the cell within the capacitor is filled with a liquid electrolyte, which acts as an electrical conductor and provides a greater capacitance than a film capacitor with the same physical size. This makes aluminum electrolytic capacitors ideal for applications requiring a large amount of capacitance in a small amount of space. Additionally, the electrolyte in an aluminum electrolytic capacitor is capable of storing more energy, which increases the capacitance rating of the device.

Working Principle

The working principle of an aluminum electrolytic capacitor is fairly straightforward. There are two plates in the device, one of which is positive and the other negative. The positive plate is covered with a thin layer of oxide, which acts as the dielectric, and between the two plates is a liquid electrolyte.

When a DC voltage is applied, the positively charged plate attracts the negative ions from the electrolyte, and the negative plate attracts the positive ions. This creates an electric field between the two plates, and the field strength increases with the applied voltage.

The electric field between the plates stores electrical energy, and this energy is released when the opposite polarity charge is applied to the plates. The amount of energy stored and released is proportional to the applied voltage and the capacitance of the capacitor.
