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.
Our Application Engineering Department is available to
advise and make recommendations. For non-standard
technical requirements and special applications, please
