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 flowo s 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), fixentewire wound, inductive.

191.000 ohms electrical resistance, 275.0 ambient temp in deg celsius at zero percent rated power, -1.000 to 1.000 resistance tolerance in percent, -55.0 to 275.0 temp range of temp coefficient in deg celsius, -30.0 to 30.0 temp coefficient of resistance in ppm per deg celsius
