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.

140.000 kilohms electrical resistance, -10.0 to 10.0 temp coefficient of resistance in ppm per deg celsius, -0.010 to 0.010 resistance tolerance in percent, -55.0 to 125.0 temp range of temp coefficient in deg celsius, 145.0 ambient temp in deg celsius at zero percent rated power
