S Series High Precision Foil Resistor with TCR of 2.0 ppm/C, Tolerance of 0.005 % and Load Life Stability of 0.005 % FEATURES Temperature coefficient of resistance (TCR): - 55 C to + 125 C, 25 C ref. - S10XC / D series: 2 ppm/C typical (see table 1) - S10XK series: 1 ppm/C typical (see table 1) Power rating: to 1 W at + 125 C Resistance tolerance: to 0.005 % (50 ppm) Load life stability: 0.005 % at 70 C, 2000 h at rated power Resistance range: 0.5 to 1 M (for higher or lower values, please contact Application Engineering) INTRODUCTION Vishay Foil resistors are not restricted to standard values specific as required values can be supplied at no extra Bulk Metal Foil (BMF) technology outperforms all other cost or delivery (e.g. 1K2345 vs. 1K) resistor technologies available today for applications that Electrostatic discharge (ESD) at least to 25 kV require high precision and high stability. Non inductive, non capacitive design This technology has been pioneered and developed by Rise time: 1 ns effectively no ringing Vishay Foil Resistors (VFR), and products based on this Current noise: 0.010 V /V of applied voltage (< - 40 dB) RMS Thermal EMF: 0.05 V/C technology are the most suitable for a wide range of Voltage coefficient: < 0.1 ppm/V applications. BMF technology allows the production of Low inductance: < 0.08 H customer-oriented products, designed to satisfy specific Non hot-spot design challenging technical requirements. Terminal finishes available: lead (Pb)-free, tin/lead alloy The S series of BMF resistors offers low TCR, excellent load Matched sets are available on request (TCR tracking: to 0.5 ppm/C) life stability, tight tolerance, fast response time, low current Prototype quantities available in just 5 working days noise, low thermal EMF and low voltage coefficient, all in one or sooner. For more information, please contact resistor. foil vpgsensors.com The S series is virtually insensitive to destabillizing factors. For better TCR performances please review the datasheets for the Z Series and Z203 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. The standard design of these resistors provides a unique combination of characteristics found in no other single resistor.
