(300 mm2) of termination pad or trace area (2 oz. copper) connected to each end of the resistor. Maximum chip temperature is 150C. Use Derating Curve to derate appropriately for the maximum ambient temperature and for the temperature limitations of the adjacent materials. Note 2: Thermal Resistance - In High Power Applications where the circuit board material provides high heat sinking benefits (such as IMS, Alumina, or other) the thermal resistance of the chip resistor is useful to establish the maximum power capability of the chip resistor in the application. The film temperature is measured at the center of the resistor element and the solder pad temperature is measured at the center of the termination pad (point X in the recommended circuit layouts shown below). Maximum temperature of the chip resistor (at the center of chip) should not exceed 150C through the temperature range of the application.
