Power Rating Notes -

Power Derating Curve

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 :

R_qH= T_MAX- ( P x R_qR) - T_A

Where: R_qH= Thermal Resistance of Heatsink ( K/W )

R_qR= 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 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 ).
