INTRODUCTION
The SMRxDZ is an ultra high 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. One of the important parameters influencing
stability is the Temperature Coefficient of Resistance
(TCR). Although the TCR of foil resistors is considered
