Type:  0

Definition:  An item generally consisting of one or more turns of wire or similar conductive material (in special cases it may be considered as a partial turn). It is specifically designed to concentrate magnetic flux generated by the flow of an electric current, to induce in itself an electromotive force, and to add or subtract inductive reactance in a circuit. It may include tuning devices, integral resistors and capacitors; however, excludes:FILTER (as modified). For coils wound on resistors which are designed to be inserted into the circuit of a radio frequency stage to suppress high frequency parasitic oscillations, see SUPPRESSOR, PARASITIC..

Description:  1. (Electrical) An item generally consisting of one or more turns of wire or similar conductive material (in special cases it may be considered as a partial turn). It is specifically designed to concentrate magnetic flux generated by the flow of an electric current, to induce in itself an electromotive force, and to add or subtract inductive reactance in a circuit. Excludes: Winding (1). In selecting appropriate modifier for a coil contained in a complex or assembled item, use name of immediate next higher component of which the coil is a direct part. For example, a coil for a relay which is part of a STARTER, MOTOR or a CONTROLLER (as modified) would properly be assigned the item name COIL, RELAY.
