In order to improve thermal conductivity, surfaces in contact (ceramic, heatsink) should be coated with a silicone grease (type Bluesil Past 340 from Blue Star Silicones). Thermal film (type Q-pad II from Berquist) is also possible, easier and faster to install than grease but with a lower efficiency for the power dissipation • The fastening of the resistor to the heatsink is under pressure control of two screws tightened at 2 Nm for full power availability LPS 1100 Tightening Torque on Heatsink 2 Nm • 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 AND THE THERMAL INTERFACE The user must choose the heatsink according to the working conditions of the component (power, room temperature). Maximum working temperature must not exceed 200 °C. The dissipated power is simply calculated by the following ratio: ΔT P = --------------------------------------------------------------------------------------------[ R th (j - c) ] + [ R th (c - h) ] + [ R th (h - a) ] P: Expressed in W ΔT: Difference between maximum working temperature and room temperature or fluid cooling temperature Rth (j - c): Thermal resistance value measured between resistive layer and outer side of the resistor. It is the thermal resistance of the component: 0.039 °C/W Rth (c - h): Thermal resistance value measured between outer side of the resistor and upper side of the heatsink. This is the thermal resistance of the interface (grease, thermal pad), and the quality of the fastening device Rth (h - a): Thermal resistance of the heatsink Example: Rth (c - h) + Rth (h - a) for LPS 1100 power dissipation 850 W at +18 °C fluid temperature ΔT ≤ 200 °C - 18 °C = 182 °C ΔT 182 R th (j - c) + R TH (c - h) + R TH (h - a) = ------- = ---------- = 0.214 °C/W P 850 R th (j - c) = 0.039 °C/W R th (c - h) + R th (h - a) = 0.214 °C/W - 0.039 °C/W = 0.175 °C/W Revision: 13-Apr-2021 Document Number: 50059 2 For technical questions, contact: sferfixedresistors@vishay.com THIS DOCUMENT IS SUBJECT TO CHANGE WITHOUT NOTICE.
