NOTES:

1. Dimensions are in inches.

2. Unless otherwise specified, tolerance is �.005 (.13 mm).

3. Metric equivalents (to the nearest .01 mm) are given for general information only and are based upon

1 inch = 25.4 mm.

4. The entire slot of the actuating screw must be above the surface of the unit.

3.3 Power rating. The power rating shall be .25 watt for characteristic C and characteristic F.

3.4 Terminals. Characteristic C and characteristic F are available with P-type, W-type, and X-type terminals.

3.5 Nominal resistance value and maximum rated ac or dc working voltage. Nominal resistance values and

maximum rated ac or dc working voltages shall be as specified in table I.

3.6 Actual effective electrical travel. Actual effective electrical travel shall be 10 turns minimum, and 25 turns

maximum.

3.7 Operating torque. Operating torque shall be a maximum of 3 ounce-inches.

3.8 Pure tin. The use of pure tin, as an underplate or final finish, is prohibited both internally and externally. Tin

content of resistor components and solder shall not exceed 97 percent, by mass. Tin shall be alloyed with a

minimum of 3 percent lead, by mass (see 6.4).
