CSM3637S Bulk Metal® Foil Technology High Precision, Current Sensing, Power Surface Mount, Metal Strip Resistor with Improved Stability 0.05 %, Resistance Value from 10 m, Rated Power to 2 W and TCR to 0 ± 20 ppm/°C FEATURES  Temperature coefficient of resistance (TCR): (- 55 °C to + 125 °C, + 25 °C ref.) ± 20 ppm/°C maximum  Load life stability to ± 0.05 % (70 °C, 2000 h at rated power)  Power rating: 2 W  Resistance tolerance: ± 0.2 % INTRODUCTION  Resistance range: 10 m to 100 m The CSM3637S is a low value current sense resistor, providing power and precision in a four terminal, surface mount configuration. Its all welded construction is made up of a Bulk Metal® resistive element with plated copper terminations.  Vishay Foil resistors are not restricted to standard values; specific “as required” values can be supplied at no extra cost or delivery (e.g. 10.2345 m vs. 10 m) There are many current sense resistors on the market, until now the combination of very stable and precise resistors with low TCR as much as 0 ppm/°C ± 20 ppm/°C, tight tolerance of ± 0.2 % and excellent load life stability of ± 0.05 % (2000 h, + 70 °C at rated power) were not easily available. The key performance of the new CSM3637S is stability, which is the ability of this resistor to maintain its value with time under nominal load at various environmental conditions. These specifications are based on tests performed in accordance with methods prescribed by appropriate MIL-PRF standards. The four terminal device separates the current leads from the voltage drop sensing leads. This configuration eliminates the effect of the lead wire resistance from points A to B and C to D. A key feature of the CSM3637S is its low thermal EMF design. The welded terminals make intimate contact with the chip thereby minimizing temperature variations. Vishay Foil Resistors’ application engineering department is available to advise and make recommendations.
