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.

General Information for Type CC - Style FC and Style WB - Chip Resistors

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.
