Electrolytic Capacitor, 2.2µF, 100 Volts

The 2.2µF 100V Electrolytic Capacitor is a polarized passive electronic component used for energy storage, filtering, signal coupling, and voltage stabilization in electronic circuits. It has a capacitance value of 2.2 microfarads (µF) and a maximum voltage rating of 100 volts (V), making it suitable for medium-voltage electronic applications.

An electrolytic capacitor uses an electrolyte and a thin oxide layer to achieve a higher capacitance value compared to ceramic or film capacitors of similar size. It is commonly used in circuits where a moderate amount of energy storage and filtering is required.

Specifications

• Capacitance: 2.2µF

• Voltage Rating: 100V DC

• Type: Electrolytic Capacitor

Working Principle

The capacitor stores electrical charge between two conductive plates separated by an insulating electrolyte material. When voltage is applied, the capacitor charges and stores energy. When required, it releases the stored energy back into the circuit.

In electronic circuits, the 2.2µF capacitor is often used to block unwanted DC signals while allowing AC signals to pass, making it useful for signal coupling applications. It can also smooth voltage fluctuations and reduce electrical noise in power circuits.
