be to scale
The SMRC1D is a truly precision molded surface mountable
resistor. It utilizes the Bulk Metal® Foil technology for
the resistive element with its inherent low TCR and long term
stability. This surface mountable product affords similar
performance to the time tested VSR molded through hole
product.

Voltage division with tight tracking < 5ppm/°C can be achieved
with 2 randomly selected units even with a large ratio between
the two values.

The molded SMRC1D, while slightly larger and heavier than
the Bulk Metal® Foil VSM surface mountable chip resistor, has
a rugged construction capable of withstanding significant thermal
cycling and allows for board installation without concern for
tolerance shifts due to manufacturing processes or mechanical
stresses.
