1 / 5 page VSA101 (Z-Foil) Vishay Foil Resistors Document Number: 63143 For any questions, contact: foil@vishay.com www.vishay.com Revision: 03-Nov-08 1 Ultra High Precision Axial 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 INTRODUCTION The VSA101 Axial Bulk Metal® Z-foil resistor is Vishay’s answer to the industry’s demand for ultra-high precision resistors with axial terminations. The Z-foil technology provides a significant reduction of the resistive component’s sensitivity to ambient temperature variations (TCR) and applied power changes (PCR). This, along with all the additional Z-foil benefits presented in the features section, allows designers to guarantee the highest 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.
