1 / 5 page Z201 (Z-Foil) Vishay Foil Resistors Document Number: 63113 For any questions, contact: foil@vishay.com www.vishay.com Revision: 19-Apr-07 1 Ultra High Precision Z-Foil Resistor with TCR of ± 0.05 ppm/°C, PCR of 5 ppm at Rated Power, Tolerance of ± 0.005 % and Load Life Stability of ± 0.005 % INDUSTRY BREAKTHROUGH Any value at any tolerance available within resistance rage INTRODUCTION The Z201 (0.150" lead spacing) and Z201L (0.200" lead spacing) Bulk Metal® Z-Foil resistors represent an industry breakthrough. This is the 3rd in a series of ultra-precision resistors since the first Bulk Metal® Foil resistor was introduced by Vishay in 1962. Each represents an improvement on the earlier model. The TCR slope of the Z201 is 0.2 ppm/ °C (- 55 °C to + 125 °C, + 25 °C Ref.) and is an order of magnitude better than the original S102C. The Bulk Metal® Z-Foil resistor is the ultimate choice in the most demanding analog applications. The Z-Foil technology provides a significant reduction of the resistive component’s sensitivity to ambient temperature variations (TCR) and applied power changes (PCR). Designers can now guarantee a high degree of stability and accuracy in fixed-resistor applications using solutions based on Vishay’s revolutionary Z-Foil technology. Our Application Engineering Department is available to advise and to make recommendations. For non-standard technical requirements and special applications, please contact us.
