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 CHART

The temperature of the case 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.
