EET-UQ2S221BA

Aluminum electrolytic capacitors are electrochemical capacitors composed of an anode that is made of a pure aluminum foil that is coated with an oxide layer and a cathode made of an aluminum foil that has an electrolyte containing an ionic solution. The EET-UQ2S221BA capacitor is a Snap-in style aluminum electrolytic capacitor that has low ESR, long life, and low impedance characteristics. It is offered with a rated capacitance of 22μF, a rated voltage of 16V, and a ripple current of 70mA.

The EET-UQ2S221BA capacitor is suitable for many applications including power switching circuits, computers, automobiles, general consumer electronics, printers, and white goods.

The working principle of the EET-UQ2S221BA capacitor can be explained by referencing the formation of a built-in electric double layer in the aluminum oxide film. This process is known as anisotropic electrolysis. It occurs when the oxide film is polarized by an electric field, and generates an electric double layer which encapsulates the contacts of the oxide film.

The contact of the oxide film itself is a part of anodic reaction during anode polarization. The oxide film itself is the contact for the current, and because of this, both electron and ions at the oxide film accumulate together. This process forms a distributed and low-resistance electric contact between the oxide film and the electrolyte, thus the EET-UQ2S221BA capacitor is able to store electrical energy.

The EET-UQ2S221BA capacitor also has other features that make it suitable for various applications. These include temperature compensation, so that the capacitance does not vary with temperature, and heat dissipation which is greater than conventional capacitors. Additionally, this capacitor is lead-free, RoHS compliant, and halogen free, making it safe for use in all types of electrical environments.

In conclusion, the EET-UQ2S221BA capacitor is an aluminum electrolytic capacitor that has excellent features and performance characteristics that make it suitable for a wide range of applications. It has low ESR, long life, and low impedance that allows for higher power handling capability, and its excellent temperature compensation and heat dissipation capabilities make it ideal for high power circuit design. Additionally, its lead-free, RoHS compliant, and halogen free makes it safe for use in practically any electrical environment.
