mended for values below 0.20ΩFig. 1B: Kelvin layout
recommended for higher

Type CC Low Resistance Precision Chip Resistors
Style FC - Flip Chip Version is a surface mount version with solderable pads for flip chip soldering.
Note 1: General Applications - The power rating
for general applications is based upon 0.5 sq. in.
(300 mm2) of termination pad or trace area (2 oz.
copper) connected to each end of the resistor.
Maximum chip temperature is 150°C. 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 150°C through
the temperature range of the application.
