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,
heatsink) should be coated with a silicone grease (type Bluesil Past 340 from BlueStar Silicones) or a thermal film (type Q
pad II) easier and faster to install than the grease.
• 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 heatsink mounting
- 2 screws TH M4 x 6/6 and 2 M4 contact lock washers for connections
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:

RTH (j - c) + RTH (c - h) + RTH (h - a) = ------ = -------- = 0.58 °C/W
RTH (j - c) = 0.112 °C/W
RTH (c - h) + RTH (h - a) = 0.58 °C/W - 0.112 °C/W = 0.468 °C/W
OVERLOADS
In any case the applied voltage must be lower than UL = 5000 V.
Short time overload: 2 x Pr/10 s
Accidental overload: The values indicated on the following graph are applicable to resistors in air or mounted onto a heatsink.
