The underside of the flange should be brushed with thermal grease prior to being fastened to the heat sink with mounting screws. The thermal grease will fill any air gaps and help to keep a good thermal contact. Termination/Resistor Tabs (1 for Termination, 2 for Resistors) Circuit Board Heat Sink/Ground Plane Flange Pre-tin the tab prior to installation. Position the tab over the circuit and solder in place. Ensure that the temperature on the surface of the flange does not exceed 110 ˚C when running at 100 % of load. If the temperature increases then derate the power. REV. 09/09 *RoHS Directive 2002/95/EC Jan 27 2003 including Annex. Specifications are subject to change without notice.
