RECOMMENDATIONS FOR MOUNTING ONTO A HEATSINK
• Surfaces in contact must be carefully cleaned.
• The heatsink must have an acceptable flatness: From 0.05 mm to 0.1 mm/100 mm.
• Roughness of the heatsink must be around 6.3 µm. In order to improve thermal conductivity, surfaces in contact (alumina,
• The fastening of the resistor to the heatsink is under pressure control of two screws tightened at 2 Nm for full power availability.
• The following accessories are supplied with each product: 2 screws CHC M4 x 25 class 8.8 and 2 M4 contact lock washers for
CHOICE OF THE HEATSINK
The user must choose the heatsink according to the working conditions of the component (power, room temperature). Maximum
working temperature must not exceed 155 °C. The dissipated power is simply calculated by the following ratio:

Difference between maximum working temperature and room temperature
Thermal resistance value measured between resistive layer and outer side of the resistor. It is the thermal
resistance of the component: (see specifications environmental paragraph).
Thermal resistance value measured between outer side of the resistor and room temperature. It is the thermal
resistance of the thermal interface, the heatsink (type, shape) and the quality of the fastening device.
