DSM 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 • Temperature Coefficient of Resistance (TCR): Absolute: ± 2 ppm/°C typical (- 55 °C to + 125 °C, + 25 °C Ref.) Tracking: 0.5 ppm/°C typical PR O DU CT Pb-free Any value at any ratio available within resistance range INTRODUCTION Bulk Metal® Foil Technology out-performs all other resistor technologies available today for applications that require High Precision and High Stability. This technology has been invented, patented and pioneered by Vishay. Products based on this technology are the most suitable for a wide range of appilcations. BMF technology allows to produce customer oriented products designed to satisfy challenging and specific technical requirements. Model DSM offers Low TCR (both absolute and tracking), Excellent Load Life Stability, Tight tolerance, Excellent Ratio Stability, and Low Current Noise, all in one package. IM PR O VE D The DSM surface mount divider provides a matched pair of Bulk Metal® 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.
