Aluminum Electrolytic Capacitors

A capacitor can be broadly defined as an electrical device consisting of two conducting surfaces separated by a dielectric material. A very common type of capacitor is the aluminum electrolytic capacitor. It makes use of the physical properties of aluminum oxide to store a charge, and is composed of aluminum electrodes in a liquid electrolyte contained in a sealed can.

277LMB160M2AC is an aluminum electrolytic capacitor with a capacitance value of 160 μF and a maximum operating voltage of 160 volts. It is widely used in DC power systems, SCR applications, and high-voltage power supplies, as well as many other applications.

Working Principle

An aluminum electrolytic capacitor works using a combination of capacitance and electrolysis. A thin layer of aluminum oxide is formed on the inner surface of an insulated aluminum foil. This layer works as a dielectric and increases the capacitance value. The electrolyte acts as an ionic conductor and a charge bearer as it provides the electrical connection between the anode and the electrolyte.

When a voltage is applied across the capacitor, the positively-charged ions within the electrolyte are attracted to the negative plate, while the negatively-charged ions are attracted to the positive plate. This creates a charge on the plates, which then further increases the capacitance value. The previously formed insulating layer of oxide further increases the capacitance, as it prevents the electrons from traveling between the plates.

Another important factor is the charge-storage mechanism of the aluminum oxide. The ions in the electrolyte are attracted to the negative plate, where they become embedded in the oxide layer and stored as charged ions. Consequently, when the positive plate is connected to ground, the charge stored in the oxide layer is available to the capacitor.
