A passive component is an electronic component which can only receive energy, which it can either dissipate, absorb or store it in an electric field or a magnetic field. Passive elements do not need any form of electrical power to operate. The items related to this field that we can supply are as follows:

Antennas

Audio Transformers / Signal Transformers

Capacitors

EMI Filters / EMI Suppression

Frequency Control & Timing Devices

Inductors, Chokes & Coils

Potentiometers, Trimmers & Rheostats

Resistors
