National Item Identification Number:
012531818
Description:
RESISTOR,FIXED,WIRE WOUND,INDUCT
Detail:
INC 37404 REINSTATED ON 010303~A resistor whose ohmic value cannot be adjusted or varied. The resistance element consists of high resistance wire (or ribbon) either wound on an insulated form or constructed so as to be self-supporting. The items must have inherent characteristics of inducing little or no self-inductance. Opposition to current flow is an inherent property of the resistance wire and is manifested by the heat dissipation in the resistor. Excludes SUPPRESSOR, IGNITION INTERFERENCE. See also RESISTOR (1), FIXED, WIRE WOUND, INDUCTIVE.
