Aluminum electrolytic capacitors, also known as electrolytic capacitors, polarized capacitors and aluminium electrolytic, are electrochemical energy storage components that store energy in the form of static electricity. Their construction consists of two or more conductive layers separated by an “ionically conductive medium” – usually an aluminum or aluminum oxide electrolyte. The application field of these capacitors is wide and includes audio crossover networks, line-level coupling, microphone selection, power decoupling, and radio frequency circuits. The working principle of aluminum electrolytic capacitors is through the two conductive layers acting as an anode and a cathode, capacitors can store energy through the process of electrochemical reaction.

The anode of an aluminum electrolytic capacitor is usually made from an aluminum foil with a surface oxide layer, and the cathode is made commonly from aluminum or other conductive materials. When a voltage is applied to the anode and cathode of the capacitor, a current passes through the electrolyte and causes the electrochemical reaction. The electrons of the anode are attracted to the positive charge of the cathode, forming an ionic bond that holds the energy being stored. The amount of energy stored is determined by the amount of charge passing through the capacitor and the strength of the dielectric material.

Aluminum electrolytic capacitors are typically employed in a variety of tasks involving electrical systems as either filter capacitors or decoupling capacitors. Filter capacitors, which are designed to smooth out power supply voltage ripples from electrical systems, are commonly used in motor-operated equipment, such as air conditioners and electric refrigerators, for example. Decoupling capacitors are employed to reduce spikes and provide more stable electrical systems, such as found in cell phones, computers, and automotive electronics.

Aluminum electrolytic capacitors are also widely used in power regulation, linear signal filtering, and dynamic limits, as well as many other applications. Low-valued capacitors can be found in power supplies, and as the capacitance value increases, they can be used in switchmode power supplies, such as those found in USB power adapters and other in-line solutions. A capacitor of even higher value can also be used for snubbing and damping applications to reduce the loads of inductors and motors.

With an increasing number of applications and designs featuring aluminum electrolytic capacitors, it is critical for consumers and engineers to select the correct capacitor types for their desired performance.
