2R, 3R, 4R (Z-Foil Technology) Vishay Foil Resistors Ultra High Precision Z-Foil Voltage Divider and Network Resistor with TCR Tracking to 0.1 ppm/C and Resistance Match to 0.005% (50 ppm) FEATURES P R O D U C T Any value at any tolerance available within resistance range INTRODUCTION The 2R, 3R, 4R Resistor Networks are the designers first choice for ultra high precision, stable and reliable Voltage Divider or Network. The Z-Foil Technology provides a significant reduction of the resistive components sensitivity to ambient temperature variations (TCR) and applied power changes, self-heating (PCR). 0.05 ppm/C Absolute TCR removes errors due to temperature gradients. The 2R, 3R, 4R provide a unique, inherent combination of performance characteristics resulting in excellent performance and high reliability, satisfying the needs of today's expanding requirements. The availability of low absolute TCR and low PCR, provides a good cost solution for the variability of other components when compiling the total error budget.
