SMR1DZ/SMR3DZ (Z-Foil) Vishay Foil Resistors Ultra High Precision Z-Foil Molded Surface Mount Resistor with TCR down to ± 0.05 ppm/°C, PCR of ± 5 ppm at Rated Power, Flexible Terminations, and Load Life Stability of ± 0.005 % (50 ppm) FEATURES PR O DU CT 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 extremely low, this characteristic has been further refined over the years. The SMRxDZ utilizes ultra high precision Bulk Metal® Z-Foil. IM PR O VE D 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.
