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 four screws (not supplied).
• In order to improve the dissipation, either forced-air cooling or liquid cooling may be used.
• Do not forget to respect an insulation value between two resistors (dielectric strength in dry air 1 kV/mm).
CHOICE OF THE HEATSINK
The user must choose according to the working conditions of the component (power, room temperature).
Maximum working temperature must not exceed 125 °C. The dissipated power is simply calculated by the following ratios:
