Capacitor

maker

A capacitor is a passive electrical component that stores energy in an electric field.

expanded

Capacitors are employed in electronic circuits to temporarily store electrical charge, manage power supply by smoothing voltage fluctuations, and filter signals. They are essential in timing applications and for providing power conditioning in electronic devices, ensuring operational stability and efficiency.

examples

A 10 µF (microfarad) capacitor used in a power supply circuit to smooth out voltage spikes.

Commonly used in AC to DC power converter circuits within consumer electronics like computers or television sets.

A 1000 pF (picofarad) capacitor used in radio frequency (RF) circuits for signal filtering.

Typically found in RF modulation circuits of wireless communication devices.
