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 facing 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.
