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.
