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.  
Non hot spot design  
Current Noise: < - 40dB  
Rise time: 1ns without ringing  
Non Inductive: < 0.08µH  
Voltage Coefficient < 0.1 ppm/V

Terminal Finishes available:  
Lead (Pb)-free  
The ꢁR, 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.
