The NPR 2-T126 Series Foil Resistors must be attached to a
suitable heatsink. The maximum internal resistor temperature
is 155°C (120°C for the NPP 2-T126).
To specify an appropriate heatsink use the following formula :
RqH = TMAX - ( P x RqR ) - TA
P
Where: RqH = Thermal Resistance of Heatsink ( K/W )
RqR = Thermal Resistance of Resistor ( K/W )
TMAX = Maximum Temperature of Resistor
TA = Ambient Temperature of Heatsink ( °C )
P = Power Through Resistor ( W )

Mounting Notes -
The NPR 2-T126 Series 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 ).
