Power Rating Notes -
The NPS Series Resistors must be attached to a suitable heat -
sink. The maximum internal resistor temperature is 175°C.
To specify an appropriate heatsink use the following formula :
R q H = T MAX - ( P x R q R ) - T A

Temperature of the backplate (°C)
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 )
