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 solder
pad temperature at the center of the solderable pedestal (point X in the recommended circuit
layout 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

Type CD Low Resistance Precision Chip Resistors
Style FC - Flip Chip version for surface mount applications.
Style WB - Wire Bond version for hybrid applications with metallized
back surface for solder down heat sinking of the chip, includes bondable
termination pedestals to receive aluminum wire bonds.
Resistance as low as 0.010 ohm at ±1%.
Pedestal terminals in this design provide an ultra low resistance
connection pad which maintains the precision 0.010Ω ±1% at the point
of customer Kelvin connection to the resistor chip. The pedestal terminal
with its copper core also provides heat spreading which enhances the
high power handling capability.
Thermal resistance is provided to optimize high power designs when
utilizing higher thermal conductivity circuit board substrates such as IMS
or Alumina.
High pulse handling and overload capability.
Low inductance provides excellent high frequency and pulse response.
