Type CD Low Resistance Precision Chip Resistors
Page 1 of 2
Low Resistance Chip down to 0.010Ω at ±1% with unique Pedestal Terminal Design
for Current Sense in Hybrid and SMT Applications
Type CD Low Resistance Precision Chip Resistors utilize the proven Caddock
Micronox® resistance ï¬lms to achieve the unique low resistance range in this
family. The special performance features of the Type CD Low Resistance
Precision Film Resistor include:
⢠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.
Style FC - Flip Chip Version is a surface mount version with solderable pedestal terminals for ï¬ip chip soldering.

Note 2: Thermal Resistance - In High Power Applications where the circuit board material
provides high heat sinking beneï¬ts (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 ï¬lm 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.
