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 m. In order to improve thermal conductivity, surfaces in contact (alumina, heatsink) are coated with a silicone grease (type Sl 340 from Rhne-Poulenc or Dow 340 from Dow Corning). The fastening of the resistor to the heatsink is under pressure control of two screws tightened at 4 Nm for full power availability. RPS 500 Tightening Torque on Heatsink 4 Nm The following accessories are supplied with each product: 2 off CHC M4 x 16/16 class 8.8 for heatsink mounting, 2 off TH M4 x 6/6 and 2 M4 contact lock washers for connections. 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 ratio: T P = ----------------------------------------------------------------------------------------------------- R ++R R th (j - c) th (c - h) th (h - a) P: Expressed in W T: Difference between maximum working temperature and room temperature R : Thermal resistance value measured between resistive layer and outer side of the resistor. It is the thermal th (j - c) resistance of the component: 0.11 C/W. R : Thermal resistance value measured between outer side of the resistor and upper side of the heatsink. This is the th (c - h) thermal resistance of the interface (grease, thermal pad), and the quality of the fastening device. R : Thermal resistance of the heatsink. th (h - a) Revision: 05-Jun-2019 Document Number: 50047 2 For technical questions, contact: sferfixedresistors vishay.com THIS DOCUMENT IS SUBJECT TO CHANGE WITHOUT NOTICE.
