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. Exclut s suppressor, ignition interference. See also resistor (1), fixed, wire wound, noninductive.

49.900 ohms electrical resistance, -20.0 to 20.0 temp coefficient of resistance in ppm per deg celsius, -1.000 to 1.000 resistance tolerance in percent, -55.0 to 275.0 temp range of temp coefficient in deg celsius, 275.0 ambient temp in deg celsius at zero percent rated power
