Aluminum Electrolytic Capacitors are a type of electrochemical capacitor that rely on the electrolytic process for their electrical properties. They are characterized by their low cost, high capacitance ratio, and high energy density. The capacitance of an aluminum electrolytic capacitor is often expressed in Farads (F). This represents a unit of electric capacity.

The UCY2C221MHD3TN is an Aluminum Electrolytic Capacitor that is most commonly used as an audio crossover capacitor. It provides a low-ESR (equivalent Series Resistance) and high ripple current rating, making it ideal for a wide range of audio applications. The capacitance value of this aluminum electrolytic capacitor is 220uF and its maximum working voltage is 16V.

The working principle of aluminum electrolytic capacitors is quite simple. It consists of two aluminum foils which are separated by a thin layer of aluminum oxide. The two foils act as the electrodes of the capacitor and the aluminum oxide acts as an dielectric material. When a voltage is applied across the capacitor, the electric charge is stored in the ceramic dielectric layer. This creates an electric field which can store energy. The higher the voltage applied, the higher the capacitance of the capacitor.

Aluminum electrolytic capacitors are widely used in a variety of consumer, industrial, and automotive applications. Consumer applications include audio circuits, power supplies, and consumer electronic devices such as televisions and computers. Industrial applications include motor control circuits and voltage regulators. Automotive applications include alarms, audio systems, and ECUs (Engine Control Units).

The UCY2C221MHD3TN aluminum electrolytic capacitor has a temperature range of -25C to +85C and a maximum ripple current rating of 550mA.
