Aluminum electrolytic capacitors are found in a wide range of applications, from consumer electronics and automotive systems to power supplies, lighting, and industrial equipment. The working principle of an aluminum electrolytic capacitor, such as the E82D201VNN122MA50T, is based on anodic oxidation of aluminum. This creates a thin, highly porous oxide film on the aluminum plate that acts as the dielectric.

The capacitor consists of an anode (positive terminal), caps (negative terminals), and a separator. A wet dielectric medium such as ethanol, propylene glycol, or isopropanol is applied to the anode. The two terminals (anode and caps) are connected by means of an electrolyte solution permeating through the aluminum oxide film. An electric field is generated by the applied voltage, which causes ions to migrate within the electrolyte solution and assemble into an electric double-layer (EDL) at the anode surface.

The EDL acts as a dielectric material, with the energy stored in the electric field, forming the capacitor. The voltage rating of the capacitor is determined by the maximum electric field that the oxide film can withstand. The higher the voltage rating, the thicker the dielectric film and the greater the energy that can be stored. Additionally, aluminum electrolytic capacitors are available in a variety of capacitances, which means they can be used in an applications requiring varying levels of energy storage.

A wide variety of aluminum electrolytic capacitors can be used in applications such as switching power supplies, HVAC systems, automotive electronics, lighting, and instrumentation equipment. The E82D201VNN122MA50T is a radial-lead aluminum electrolytic capacitor with a voltage rating of 16V and capacitance of 22uF. It is designed for use in automotive and industrial applications where high capacitance and low equivalent series resistance (ESR) are required. Typical applications for this part include filters, power supplies, automotive electronics, and instrumentation.

Aluminum electrolytic capacitors are widely used in various electronic devices due to their low cost, long service life, compact size, and good performance. They offer excellent high frequency characteristics, low ESR, and high ripple current rating, making them an ideal choice for a variety of applications. The E82D201VNN122MA50T is a compact, yet reliable capacitor that can be used for a host of automotive and industrial applications.
