Note 3: 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 soldered interface with the circuit board. Maximum
temperature of the chip resistor (at the center of chip) should not exceed 150°C through the
temperature range of the application.

Solder attachment note:
Style FC has a bare ceramic back surface.
The recommended solders for flip chip
solder attachment are 62Sn / 36Pb / 2Ag,
96.5Sn / 3.5Ag, or standard Sn / Ag / Cu
solder alloys.
Style WB has a metallized back surface for
soldering to a substrate or a heat sink. The
recommended solders to be used are
62Sn / 36Pb / 2Ag, 96.5Sn / 3.5Ag, or
standard Sn / Ag / Cu solder alloys.
Packaging information:
Style FC, flip chip resistors, are shipped with the bare
ceramic side up in the pocket, with the solderable pads fac-
ing down.
Style WB, wire bondable resistors, are shipped with the
wire bondable pads facing up in the pocket.
The illustration shows the orientation of the CC1512 and
CC2015 chip resistors in the tape. The CC2520 chip resistors
are rotated 90° from what is shown in the illustration.
