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 SI 340 from Rhône-Poulenc or Dow 340 from Dow Corning) 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:
P: Expressed in W ΔT: Difference between maximum working temperature and room temperature R

Example:
R ΔT 155 °C - 50 °C = 105 °C R R R

OVERLOADS
In any case the applied voltage must be lower than
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.
ENERGY CURVE
UL = 5000 V.
POWER RATING
The temperature of the case should be maintained within the limits specified in the following figure. To optimize the thermal conduction, contacting surfaces should be coated with silicone grease or thermal film, and heatsink mounting screws tightened to 2 Nm.
