A resistor in which a sliding or rolling contact moves over an exposed area of the resistive element to change the ohmic value of the output. The functional tolerance (linearity) of the output is equal to or less than plus or munus 1 percent on linear outputs. Specified outputs such as sine, cosine, tangent, and the like, shall be considered to be precision. For items having manually positioned taps designed to be set and fixed prior to use, see resistor, adjustable, for items with step by step variation, see rheostat and resistor, step by step. For tandem-mounted items designed to function together as an attenuator (and rated accordingly), see attenuator, variable. Excludes:resistor (1), variable, nonwire wound; nonprecision; resistor(1), variable, nonwire wound, precision; and resistor (1), variable, wire wound, nonprecision.

-55.0 to 350.0 temp range of temp coefficient in deg celsius, -5.000 to 5.000 resistance tolerance in percent, 350.0 ambient temp in deg celsius at zero percent rated power, -260.0 to 260.0 temp coefficient of resistance in ppm per deg celsius, 750.000 ohms electrical resistance
