S Series Vishay Foil Resistors High Precision Foil Resistor with TCR of ± 2.0 ppm/°C, Tolerance of ± 0.005 % and Load Life Stability of ± 0.005 % FEATURES Any value at any tolerance available within resistance range INTRODUCTION Bulk Metal® Foil (BMF) technology outperforms all other resistor technologies available today for applications that require high precision and high stability. This technology has been pioneered and developed by VISHAY, and products based on this technology are the most suitable for a wide range of applications. BMF technology allows us to produce customer orientated products, designed to satisfy challenging and specific technical requirements. Model S Series made from Vishay BMF offers low TCR, excellent load life stability, tight tolerance, fast response time, low current noise, low thermal EMF and low voltage coefficient, all in one resistor. The S Series is virtually insensitive to destabillizing factors. The resistor element is a solid alloy that displays the desirable bulk properties of its parent material, thus it is inherently stable and noise free. Vishay’s Bulk Metal® S Series resistors are the modern generation of precision resistors. The standard design of these resistors provides a unique combination of characteristics found in no other single resistor. Our Application Engineering Department is available to advise and to make recommendations.

Standard Test Operations: 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 factory conducted “Improved Performance Testing”. The test routine is usually tailored to the users stability objectives and product that has been screened can be brought down to a potential load life of less than 50 ppm. By 100 % Inspection • Short-time overload (6.25 x rated power for 5 s) • Resistance – tolerance check • Visual and mechanical By Sample Inspection • TCR • Environmental tests per table 3 on a quarterly basis to establish performance by similarity B. Standard Test Conditions: • Lead test point: 0.5" (12.7 mm) from resistor body • Temperature: + 23 °C ± 2 °C • Relative humidity: per MIL-STD-202 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 prepared to discuss and recommend appropriate routines given the full spectrum of anticipated stresses and stability requirements.
