INTRODUCTION

The 303139, 303140 are ultra high precision molded surface

mountable resistors offering all the elements of precision;

including low TCR, tight tolerance, long term stability, low

noise, low thermal EMF, and non-measurable voltage

coefficient. One of the important parameters influencing

stability is the temperature coefficient of resistance (TCR).

Although the TCR of foil resistors is considered extremely

low, this characteristic has been further refined over the

years. These resistors utilize ultra high precision Bulk Metal

Z-Foil.

The Z-Foil technology provides a significant reduction of

the resistive element’s sensitivity to ambient temperature

variations (TCR) and to self heating when power is applied

(power coefficient).

Voltage division with tight tracking < 2 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.
