This technology has been pioneered and developed by VISHAY, 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 extremely 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 Bulk Metal(R) S Series are the modern generation of precision resistors, their design gives you a unique combination of characteristics found in no other single resistor- and they're all standard. Our Application Engineering Department is prepared to advise and to make recommendation for non-standard technical requirements and special applications, please contact us. * Low Voltage Coefficient: (see table 2) * Non Inductive: (see table 2) * Low Current Noise: (see table 2) "Noise Free Component" * Rise/Decay Time: (see table 2) * Low Thermal EMF: (see table 2) * Terminal Finishes Available: Lead (Pb)-free (Sn 100%) Tin/Lead Alloy (Sn 60%, Pb 40%) * For values below 50 please contact Application Engineering APPLICATIONS * High Precision Amplifiers * High Precision Instrumentation * Medical and Test Equipment * Industrial * Audio (High End Stereo Equipment) * EB Applications (electron beam scanning and recording equipment, electron microscopes) * Military, Airborne * Measurement Instrumentation SALES * ISRAEL: foilsales.israel@vishay.com * FRANCE/SWITZERLAND/SOUTHERN EUROPE: foilsales.eusouth@vishay.com * AMERICAS: foilsales.usa@vishay.com * ASIA/JAPAN: foilsales.asia@vishay.com * UK/HOLLAND/SCANDINAVIA: foilsales.eunorth@vishay.com * GERMANY/CZECH REPUBLIC/AUSTRIA: foilsales.eucentral@vishay.com For technical questions in the Americas, contact foilsupport1@vishay.com Document Number: 63001 For technical questions in Asia/Japan/Europe/Africa/Israel, contact foilsupport2@vishay.com Revision 31-Jan-05 www.vishay.com 71 THROUGH HOLE * Resistance Range: 0.5 to 1M S Series Vishay Foil Resistors FIGURE 1 - STANDARD IMPRINTING AND DIMENSIONS Front View L H VISHAY XXXX S102C Rear View Optional Customer Part Number Print specification, etc. if required W Date Code 01 10 Year Week Resistance Value Code XXXXXX 100R01 0.01% Tolerance ST* SW Model Number LL LS *The standoffs shall be so located as to give a lead clearance of 0.010" minimum between the resistor body and the printed circuit board when the standoffs are seated on the printed circuit board.

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 stabilty objectives and product that has been screened can be brought down to a potential load life of less than 50ppm. By 100% Inspection * Short-time overload (6.25 x rated power for 5 seconds) * 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: + 22C 2C * 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.
