Series (Z-Foil) with Zero
Hermetically Sealed Construction Ultra High Precision Z-Foil Technology Resistors with ppm/°C, Tolerance 0.001 Load Life Stability 0.005 (Metrology, Laboratory, Instrumentation, Industrial)
Temperature coefficient resistance (TCR): ppm/°C typical ref.) Resistance range: (higher lower values resistance available) Vishay Foil resistors restricted standard values; specific required" values supplied extra cost delivery (e.g. 1K2345 Power coefficient self heating": rated power with Z-foil technology Tolerance: 0.001 ppm) Load life stability 0.002 maximum 2000 chip) Load life stability, tolerance considerably improved through in-house oriented tests (PMO) Shelf life stability: least years (unaffected humidity) Electrostatic discharge (ESD) Power rating: (depending model table Non-inductive, non-capacitive design spot design Rise time: effectively ringing Current noise: Thermal EMF: 0.05 µV/°C typical Voltage coefficient: ppm/V Thermal stabilization time Non-inductive: 0.08 Terminal finish available: lead (Pb)-free, tin/lead alloy Impervious harmful environments filled Prototype quantities available just working days sooner. more information, please contact foil@vishay.com better performances, please contact
INTRODUCTION
Z-foil based filled, hermetically sealed Series resistors represent industry breakthrough. hermetic sealing eliminates ingress moisture oxygen, while acts thermal conductor, thus eliminating long term degradation elements unsealed resistors, while same time allowing device accept short periods overload without degradation. Z-Foil technology provides significant reduction resistive components sensitivity ambient temperature variations (TCR) applied power changes (PCR). When combined with hermetic sealing filling, Series resistors become most precise stable resistors available. With accuracies 0.001 ppm) resistance range from long term shelf life less than ppm, these devices virtually secondary standards that carried sets daily periodic calibration factory measurement equipment. Series also available with laboratory metrology level precision long term stability with additional in-house oriented process such chip stabiliziation, special plotting, additional treatments ultra stability special post manufacturing operations (PMO).
