OVERLOADS
In any case the applied voltage must be lower than the
maximum overload voltage of 375 V.
The values indicated on the graph below are applicable to
resistors in air or mounted onto a heatsink.

POWER RATING
The temperature of the heatsink should be maintained within
the limits specified.
To improve the thermal conductivity, surfaces in contact
should be coated with a silicone grease and the torque
applied on the screw for tightening should be around 1 Nm.
Spring clip can also be used to mount the component on an
heatsink (ex: Kunze, clip KU4-498).
