SMR1D/SMR3D
Vishay Foil Resistors
High Precision Bulk Metal ? Foil Molded Surface Mount Resistor
with TCR down to ± 2 ppm/°C , Flexible Terminations,
and Load Life Stability of ± 0.005 % (50 ppm)
FEATURES
? Temperature coefficient of resistance (TCR):
± 2 ppm°C typical (- 55 °C to + 125 °C,
+ 25 °C ref.)
? Tolerance: to ± 0.01 %
? Flexible terminations ensure minimal stress
Any value at any tolerance available within resistance range
INTRODUCTION
The SMRxD is a precision molded surface mountable
resistor offering all the elements of precision; including low
TCR, tight tolerance, long term stability, low noise, low
thermal EMF, and non-measurable voltage coefficient. It
utilizes the Bulk Metal ? Foil technology for the resistive
element with its inherent low and predictable TCR and long
term stability. This surface mountable product affords similar
performance to the time tested S series molded through-hole
product.
The flexible terminations of this product also reduce
stress transference from the PCB to the resistor.
Voltage division with tight tracking < 3 ppm/°C can be
achieved with 2 randomly selected units even with a large
ratio between the two values.
transference from the PCB due to a difference
in thermal coefficient of expansions (TCE)
