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(R) 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. For non-standard technical requirements and special applications, please contact us.

Standard Test Operations: By 100 % Inspection * * Short-time overload (6.25 x rated power for 5 s) Resistance - tolerance check Tolerance of 0.005 % and Load Life Stability of 0.005 % IMPROVED PERFORMANCE TESTING (IPT) 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. 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. * Visual and mechanical By Sample Inspection * * TCR Environmental tests per table 3 on a quarterly basis to establish performance by similarity B.

The resolution limit of existing test equipment (within the measurement capability of the equipment, or "essentially zero".) 4. V/C relates to EMF due to lead temperature difference and V/watt due to power applied to the resistor. www.vishay.com 4 For any questions, contact: foil@vishay.com Document Number: 63001 Revision: 20-Nov-07 S Series High Precision Foil Resistor with TCR of 2.0 ppm/C, Vishay Foil Resistors Tolerance of 0.005 % and Load Life Stability of 0.005 % TABLE 5 - GLOBAL PART NUMBER INFORMATION NEW GLOBAL PART NUMBER: Y000780K5000V9L (preferred part number format) DENOTES PRECISION Y VALUE R= K = k M = M AER* 0 = standard 9 = lead (Pb)-free 1 - 999 = custom Y 0 0 0 7 8 0 K 5 0 0 0 V 9 L PRODUCT CODE 0007 = S102C 0785 = S102J 0062 = S102K 0786 = S102L 0011 = S104D 5011 = S104F 0101 = S104K 4101 = S104L 0012 = S105D 4012 = S105F 0102 = S105K 4102 = S105L 0013 = S106D 0103 = S106K TYPE: S102C VALUE: 80.5 k ABSOLUTE TOLERANCE: 0.005 % TERMINATION: lead (Pb)-free PACKAGING: bulk pack RESISTANCE TOLERANCE V = 0.005 % T = 0.01 % Q = 0.02 % A = 0.05 % B = 0.1 % C = 0.25 % D = 0.5 % F = 1.0 % PACKAGING L = bulk pack FOR EXAMPLE: ABOVE GLOBAL ORDER Y0007 80K5000 V 9 L: HISTORICAL PART NUMBER: S102C T 250R00 V B (will continue to be used) S102C MODEL S102C S102J S102K S102L S104D S104F S104K S104L S105D S105F S105K S105L S106D S106K Note * For non-standard requests, please contact application engineering.
