Aluminum Electrolytic Capacitors

UUJ1A222MNQ1MS is a type of aluminum electrolytic capacitor, and its working principle and application fields are explained below.

Working Principle

Aluminum electrolytic capacitors are two-terminal components capable of storing electrical energy through an electrochemical reaction. These capacitors consist of a metal body foil, an electrolyte, and two electrodes known as an anode and a cathode. This anode usually contains an etched aluminum foil while the cathode is normally comprised of a surrounding film-like non-conductor. Aluminum electrolytic capacitors are usually polarized capacitors, meaning the direction in which they are connected will make a difference in the electrical properties of the capacitor.

When connected in an electrical circuit, the anode aluminum foil acts as a dielectric medium which is saturated with an electrolyte. This electrolyte is essential for conducting electricity between the two electrodes and forming a strong electric field within the capacitor. This electric field is responsible for the creation of electrical charge carriers or ions on the aluminum foil which, through the movement of electrons, will create an electrical charge. This charge is then stored within the capacitor and will be released when the capacitor is disconnected.

Application Fields

As aluminum electrolytic capacitors possess a large capacitance combined with a relatively low cost, they can be used in many common applications, such as filtering, timing, and positive feedback. Additionally, due to their reliable performance in different operating conditions, they are often used for providing polarized energy storage in power supplies, coupling, and decoupling devices.

UUJ1A222MNQ1MS, in particular, is a surface mount (SMT) aluminum electrolytic capacitor used in power supply and other circuitry. It has a rated capacitance of 220 microfarads, a rated voltage of 20V, and a high ripple current capability.
