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. LPS 800 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 The user must choose the heatsink according to the working conditions of the component (power, room temperature). Maximum working temperature must not exceed 175 °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 RTH (j - c): Thermal resistance value measured between resistive layer and outer side of the resistor. It is the thermal resistance of the component: (see specifications environmental paragraph). 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 - a) for LPS 800 power dissipation 180 W at +50 °C room temperature. ΔT ≤ 175 °C - 50 °C = 125 °C ΔT 125 RTH (j - c) + RTH (c - h) + RTH (h - a) = ----- = -------- = 0.69 °C/W P 180 RTH (j - c) = 0.112 °C/W RTH (c - h) + RTH (h - a) = 0.69 °C/W - 0.112 °C/W = 0.578 °C/W Revision: 14-Apr-2021 Document Number: 50054 2 For technical questions, contact: sferfixedresistors@vishay.com THIS DOCUMENT IS SUBJECT TO CHANGE WITHOUT NOTICE.

OVERLOADS POWER RATING In any case the applied voltage must be lower than UL = 5000 V. Short time overload: 1.5 x Pr/10 s Accidental overload: The values indicated on the following graph are applicable to resistors in air or mounted onto a heatsink. 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.
