Use your thermal design experience with power semiconductors in
D-Pak style power packages. This experience will help you get the most out
of this unique family of surface mount power resistors. The thermal design
issues are the same where power handling capability is based on the case
temperature which is maintained in your design.

establishing the maximum applied power. See Derating
Curve. The case temperature measurement is made on the
metal mounting tab against the molded body.
appropriately for the ambient temperature range, the thermal
resistance of the mounting surface, and the temperature
limitations of the adjacent materials (such as glass epoxy).
Derating ( thermal resistance ) is 0.200 W/°C ( 5.0°C/W ).
Power dissipation is 2.5 watts, at an ambient temperature of
25°C, when mounted on a double sided copper board (2 ounce,
G-10 or FR-4) 1 inch x 1 inch x .063 inch (thick).
