SMNH Vishay Foil Resistors Ultra High Precision Bulk Metal® Foil Technology 4 Resistor Surface Mount Hermetic Network with 0.5 ppm/°C TCR Tracking and 0.005 % Tolerance Match FEATURES • Temperature coefficient of resistance (TCR): absolute: ± 2 ppm/°C typical (- 55 °C to + 125 °C, + 25 °C ref.) tracking: ± 0.5 ppm/°C typical • Resistance range: 5 Ω to 33 kΩ INTRODUCTION Vishay model SMNH networks incorporate all the performance features of Vishay Bulk Metal® Foil technology in a product ready for surface mounting. The 8 pin gull wing side brazed DIP is the smallest ceramic package. Ceramic has the advantage of electrical isolation on the underside and high heat dissipation capability. Resistors in network form, around the operational amplifier for example, are called upon to track at changing ambient temperature, to hold ratio under power and to force the ratio changes over a period of time to be very low. The hermeticity, the location of the chips within the package and the “heat-sink effect” of the ceramic package itself help preserve uniform conditions inside it. The Bulk Metal Foil Vishay technology advantage in such a construction assures remarkable performance due to the following factors: - fundamentally low TCR - very small drift with load over time - common behavior: all drifts move in the same direction with temperature, load and time - TCR and tolerance match - excellent tracking • Vishay Foil resistors are not restricted to standard values; specific “as required” values can be supplied at no extra cost or delivery (e.g. 1K2345 vs. 1K) • Power rating: at 70 °C Entire package: 0.4 W Each resistor: 0.1 W • Resistance tolerance match: ± 0.005 % • Load life stability per resistor: 0.005 % (0.1 W at 70 °C, 1000 h) • Load life stability ratio: 0.005 % (0.1 W at 70 °C) • Shelf life stability per resistor: 0.0002 % (2 ppm) • Shelf life stability ratio: 0.0001 % (1 ppm) • Electrostatic discharge (ESD) up to 25 000 V • Short time overload ≤ 0.002 % (20 ppm) • Non-inductive, non-capacitive design • Rise time: 1 ns effectively no ringing • Thermal stabilization time < 1 s (nominal value achieved within 10 ppm of steady state value) • Current noise: 0.010 µVRMS/V of applied voltage (< - 40 dB) • Voltage coefficient: < 0.1 ppm/V The major highlights are emphasized by an excellent load life and shelf life ratio stability. • Non inductive: < 0.08 µH Vishay hermetic resistor networks are based on fabrication from a standing inventory of packages and resistor chips. This permits quick delivery of prototypes since there are no masks to design or trial processings to be made. Further, it allows any combination of values, tolerances and circuits. There are normally no engineering or setup charges, and no minimum quantities are required. Delivery can be in two weeks. (See network express prototype service.) • Terminal finish: gold plated (lead (Pb)-free) • Non hot spot design • For better performances please contact us • Available with Z-Foil technology for improved TCR to 0.2 ppm/°C • Compliant to RoHS directive 2002/95/EC The sequence of fabrication includes selection of chips, die attachment, wirebonding, value trimming, and hermetic sealing. The finished product provides the stability associated with Foil resistors in a hermetically sealed package. Hermetic sealing of Vishay’s networks enhances their already inherently stable environmental performance. The result is improved load life stability and better performance during high temperature and moisture exposure.

For purposes of determining reliability calculations, consider the characteristics shown as figures of merit and allow no more than ± 0.05 ΔR lifetime. Allow proportionately less if the severity of anticipated environmental stresses are small compared to the tests as defined in MIL-PRF-83401. • Post manufacturing operation (PMO) has the effect of minimizing ΔR’s. Consult Vishay applications engineering for details. • ΔRatio refers to the change in ratio between resistors within the network package from before, to after, the specified test.
