Function
L = Termination (50 ohms only)
R = Resistor
The mounting surface must be ?at to less
than 0.0254 mm (0.001 ”) and devoid of
scratches or burrs. The underside of the
?ange should be brushed with thermal
Termination/Resistor
Tabs (1 for Termination, 2 for Resistors)
grease prior to being fastened to the heat
sink with mounting screws. The thermal
grease will ?ll any air gaps and help to

keep a good thermal contact.
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 ?ange does not exceed 110 ?C when
running at 100 % of load. If the temperature increases then derate the power.
