Special Features:

C/o a coil, resistor and capacitor; encased; plug-in

Properties:

A grouping of two or more different discrete items, such as resistors, coils, and capacitors, electrically connected and used as a unit to couple two or more circuits in such a manner that the impedance of each circuit will be equal to the impedance into which it hooks. For items fabricated by monolithic and/or thin film techniques, see microcircuit (as modified). See also attenuator (as modified); and transformer (as modified). Excludes resistor set, matched.
