Mounting High Power Devices  
Value (see Resistance Value Table)  
The mounting surface must be flat to less  
than 0.0254 mm (0.001 ”) and devoid of  
scratches or burrs. 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.

Circuit Board

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.
