VSA101 (Z-Foil) Vishay Foil Resistors Document Number: 63143 For any q uestions, 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 sensitiv ity 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 des igners 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.

  • Temperature: + 23 °C ± 2 °C
  • Relative humidity: 35 to 65 % RH
  • Lead test point: 0.5" (12.7 mm) from resistor body IMPROVED PERFORMANCE TESTING The preceding information is based on product directly off the production line. Improved performance (meaning increased time stability with load and other stresses) is available through fa ctory conducted “Improved Performance Testing”. The test routine is usually tailored to the user’s stability objectives. A screened product can be brought down to a potential load life drift o f less than 50 ppm. For example, the data sheet “7 Technical Reasons to Specify BM F Resistive Components” shows the drift characteristics of a standard product. Various screen test routines are available and all anticipated stresses must be taken into account before settling on one specific test routine. Our Applications Engineering Department is available to discuss and recommend appropriate routines given the full spectrum of anticipated stresses and stability requirements.
