Power Rating Notes -
The PF1260 Series Thin Film Resistors must be attached to a
suitable heatsink. The maximum internal resistor temperature is
155°C.

To specify an appropriate heatsink use the following formula :
R q H = T MAX - ( P x R q R ) - T A

Where:
R q H = Thermal Resistance of Heatsink ( K/W )
R q R = Thermal Resistance of Resistor ( K/W )
T MAX = Maximum Temperature of Resistor
T A = Ambient Temperature of Heatsink ( °C )
P = Power Through Resistor ( W )
Mounting Notes -
The PF1260 Series Thin Film Resistors must be attached to
a suitable heatsink. Mount resistor using thermal grease to
a clean / flat surface. Use a compression washer to provide
150 to 300 pounds ( 665 to 1330N ) of mounting force. Torque
mounting screw to 8 in-lbs ( 0.9 Nm ).
Back plate is isolated from both pins.
