Devices that do not amplify or produce a signal.
In the semiconductor or network industry, a component that does not require any external power to function other than the signal that is being transmitted through it, as opposed to an active component, which does. See also Active component.
Example passive components of a die are resistors, capacitors and conductors.
components that do not amplify or switch signals. Examples include, capacitors, resistors, transformers, inductors, etc.
Electronic component that conducts functions and calculations provided by an active (controller) component by means of electronic switching, for example a condensor.
devices that filter, divide or combine the light signals traveling through optical fiber. They require no input power to operate on an optical signal. Couplers, isolators and wavelength division multiplexers are examples of passive components. These devices are much more labor intensive and costly to manufacture than active components.
