Federal Supply Class:
5905
National Item Identification Number:
012129478
Description:
RESISTOR,FIXED,WIRE WOUND,INDUCT
Detail:
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. Opposition to the flow of current is an inherent property of the resistance wire and is manifest by the heat dissipation in the resistor. Excludes SUPPRESSOR, IGNITION INTERFERENCE.
