The U-Series Resistors must be attached to a suitable heat-

sink. The maximum internal resistor temperature is 155°C.

To specify an appropriate heatsink use the following formula :

= T

MAX

- ( P x R

) - T

Where:

= Thermal Resistance of Heatsink ( K/W )

= Thermal Resistance of Resistor ( K/W )

MAX

= Maximum Temperature of Resistor

= Ambient Temperature of Heatsink ( °C )

P = Power Through Resistor ( W )

Temperature of the backplate(°C)
