ORDERING INFORMATION
Power Resistor Thick Film Technology
PACKAGING
Tube of 50 units
OVERLOADS
In any case the applied voltage must be lower than the maximum overload voltage of 375V.
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 heatsink should be maintained within the limits specifi ed.
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.
