passive component Last modified: Tuesday, February 26, 2008
In electrical, computer or storage systems, passive components are those that do not require electrical power to operate (e.g., not capable of power gain). This could include the chassis, capacitors, resistors or enclosures that do not require electrical power to operate but would exclude system components such as the power supply, fans, storage device, transistors, diodes and other controllers (called active components).
