Voltage coefficient <0.1 ppm/V This technology has been pioneered and developed Non inductive: <0.08 H by Vishay Foil Resistors, and products based on this technology are the most suitable for a wide range of Non hot spot design applications. Terminal finishes available: Lead (Pb)-free Tin/Lead alloy BMF technology allows us to produce Customer Orientated products designed to satisfy challenging and For better performances please contact us specific technical requirements. Available with Z-Foil technology, please see SMNZ datasheet. Model SMN offers low TCR (absolute and tracking), excellent load life stability, tight tolerance (absolute and match), excellent ratio stability, low thermal EMF, low APPLICATIONS current noise and low voltage coefficient - all in the same Instrumentation amplifiers resistor. Bridge networks The SMN Surface Mount Network is made up of 4 Differential amplifiers independent BMF resistors in a small standard molded Ratio arms in bridge circuits epoxy package with 50 MIL lead pitch (JEDEC MS-012 package). Medical and test equipment Military The electrical specification of this integrated construction R2 offers improved performance and better real estate Airborne, etc. utilization over discrete resistors and matched sets.

To increase the resistance in known increments, marked Figure 3Dimensions and Imprinting areas are cut, producing progressively smaller increases in Example in inches (millimeters) resistance. This method reduces the effect of hot spots and improves the long-term stability of Bulk Metal Foil resistors. 0.008 0.001 RATIO (0.20 0.025) TOLERANCE CODE 0.050 0.0165 0.0025 (0.42 0.064) (1.27) VALUE R1 Figure 6Land Pattern in inches (millimeters) VALUE R2 0.028 0.001 0.283 (7.19) SMN (0.71 0.025) Z +0.008 (0.2) (1) 10K Q 5K0 D V B0219 DATE 0.024 (0.61) X PIN NO. 1 IDENTIFIER CODE +0.008 (0.2) 0.197 0.005 PIN NO. 1 (5.00 0.13) 2 - 6 Z 0.095 (2.41) Y 0.068 0.005 0.008 (0.2) (1.73 0.13) 0.0075 0.0025 (0.191 0.064) Y Seating 0.050 (1.27) Plane E nominal Note (1) (1) If the If the rresistaesistance value of R1 and R2 contains mornce value of R1 and R2 contains more than 6 characters togete than her, the VCODE EX will be printed instead (see Resistance Value Code List for Popular Ratios Table) followed by 6 characters together, the VCODE will be printed instead the ratio tolerance code 0.150 (3.81) (see Resistance Value Code List for Popular Ratios Table) D nominal followed by the ratio tolerance code www.vishayfoilresistors.com For any questions, contact 4134-EN 2 foil vpgsensors.com Rev 22-Oct-2020 0.157 (3.99) Percent of Rated Wattage 0.246 0.0004 (6.25 0.1) R (ppm) R
