Capacitors (Input & Output) Component – Electrical Equipment Manufacturing

Component Specifications

Definition

Capacitors in power delivery circuitry are passive electronic components that store and release electrical energy to filter noise, smooth voltage ripples, and provide transient response in both input and output stages of power supplies, converters, and regulators.

Working Principle

Operates by storing electrical charge between two conductive plates separated by a dielectric material, with input capacitors filtering AC line noise and stabilizing DC voltage, while output capacitors reduce ripple and provide instantaneous current to loads during demand spikes.
