Notes:
1 Power rating is based on continuous full load operation at an ambient temperature of +25°C.
For resistors operated at ambient temperatures above +25°C, power rating shall be derated per the Derating Curve below.
2 Except Part Number 77083120P (12 ohms).
3 See Page 2 for Schematic 5 available part numbers.
4 P = Power Rating, R = Resistance.
