For better performances please review SMRxDZ datasheet

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.

Our Application Engineering Department is available to

advise and make recommendations. For non-standard

technical requirements and special applications, please
