VFCD1505 (Z-Foil) Vishay Foil Resistors High Precision Bulk Metal® Foil Surface Mount Voltage Divider, TCR Tracking of < 0.5 ppm/°C, Tolerance Match of 0.01 % and Stability of ± 0.005 % (50 ppm) FEATURES Bottom View INTRODUCTION Bulk Metal® Z-Foil (BMZF) technology out-performs all other resistor technologies available today for applications that require ultra high precision and ultra high stability. The new Z-Foil technology provides a significant reduction of the resistive element’s sensitivity to changes of temperature due to ambient temperature variations (TCR) and to self heating when power is applied (power coefficient). Model VFCD1505 offers low TCR (both absolute and tracking), excellent load life stability, tight tolerance, excellent ratio stability, low thermal EMF and low current noise, all in one package. 0.05 ppm/°C absolute TCR removes errors due to temperature gradients. The VFCD1505 surface mount divider provides tight tolerance matching and TCR tracking between 2 resistors simultaneously etched on one piece of foil on a common substrate. The electrical specifications of this integrated construction offers improved performances and better real estate utilization over discrete resistors and matched pairs.
