Product Details | INDUCTIVE WIRE WOUND FIXED RESISTOR

5905-01-234-2255 INC 37403 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 item must have inherent characteristics of inducing 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, NONINDUCTIVE.
