1 / 5 page DSMZ (Z-Foil) Vishay Foil Resistors Document Number: 63121 For any questions, contact: foil@vishay.com www.vishay.com Revision: 06-Aug-07 1 Ultra High Precision Bulk Metal® Z-Foil Surface Mount Voltage Divider, TCR Tracking of < 0.1 ppm/°C, PCR of ± 5 ppm at Rated Power and Stability of ± 0.005 % (50 ppm) Any value at any ratio available within resistance range INTRODUCTION Bulk Metal® Z-Foil Technology out-performs all other resistor technologies available today for applications that require ultra-high precision and ultra-high stabilitly. 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). The DSMZ offers low TCR (both absolute and tracking), low PCR, excellent load life stability, tight tolerance match, excellent ratio stability, low thermal EMF, and low current noise - all in one package. The DSMZ surface mount divider provides a matched pair of Bulk Metal® Z-Foil Resistors in a small epoxy molded package. The electrical specification of this integrated construction offers improved performance and better real estate utilization over discrete resistors and matched pairs. Our Application Engineering Department is available to advise and make recommendations. For non-standard technical requirements and special applications, please contact us. Notes 1.
