Power Rating, Watts 2 watts @ 55C derated to no load @ 105C, mounted on steel panel 1.5 watts @ 55C derated to no load @ 105C, mounted on bakelite panel Voltage Rating Determined by resistance value and wattage rating Mounting Types Available Type 110: Solder or clinch-ear mounted Type XPC-110: Vertically mounted on printed circuit board Type 111: Snap-in mounting Type 112: Eyelet or rivet mounting Tapers Available Standard: Linear taper only Rotational Torque 1/2 to 10 inch ounces (36 - 720 g-cm) Minimum Resistance At ends of rotation: 1% or 1 ohm, whichever is greater Terminals Terminals at end of CW or CCW rotation may be omitted. Refer to terminals on all types by numbers 1 and 3 as indicated on line drawings. Taps Available None Incorporated Fixed Resistor A fixed resistor can be incorporated in the Series 110 at the end of CW or CCW rotation to a minimum of 10% of the total resistance. The rotation is shortened by an amount proportional to the ratio of the fixed resistor to the total resistance. Available at extra cost.
