Z Series (Z-Foil) Vishay Foil Resistors Ultra High Precision Z-Foil Resistor with TCR of ± 0.05 ppm/°C, Tolerance of ± 0.005 % (50 ppm), Load Life Stability of ± 0.005 %, ESD Immunity up to 25 kV and Thermal EMF of 0.05 µV/°C FEATURES NEW INTRODUCTION The Bulk Metal® Foil resistor is based on a special concept where a proprietary bulk metal cold rolled foil is cemented to a ceramic substrate. It is then photoetched into a resistive pattern. Furthermore, it is laser adjusted to any desired value and tolerance. Because the metals used are not drawn, wound or mistreated in any way during manufacturing process, the Bulk Metal Foil resistor maintains all its design, physical and electrical characteristics while winding of wire or sputtering does not. Z foil resistors achieve maximum stability and near-zero TCR. These performance characteristics are built-in for every unit, and do not rely on screening or other artificial means for uniform performances. The stability of a resistor depends primarily on its history of exposures to temperature. Stability is affected by: 1. Changes in the ambient temperature and heat from adjacent components (defined by the Temperature Coefficient of Resistance, or TCR) 2. Destabilizing thermal shock of suddenly-applied power (defined by the power coefficient, or PCR) 3. Long-term exposure to applied power (load-life stability) 4. Repetitive stresses from being switched on and off In very high-precision resistors, these effects must be taken into account to achieve high stability with changes in load (Joule Effect) and ambient temperature. Vishay’s new Z-Foil technology provides an order of magnitude reduction in the Bulk Metal Foil element’s sensitivity to temperature changes - both external and internal. This technology provides an absolute TCR of ± 0.05 ppm/°C typical (instrument range: 0 °C to +60 °C), ± 0.2 ppm/°C typical (military range: - 55 °C to + 125 °C, + 25 °C ref), and a PCR of 5 ppm at rated power. In order to take full advantage of this TCR improvement, it is necessary to take into account the differences in the resistor’s response to each of the above-mentioned effects. The Z series has been developed to successfully deal with these factors. • Temperature coefficient of resistance (TCR): - ± 0.05 ppm/°C typical (0 °C to + 60 °C) - ± 0.2 ppm/°C typical (- 55 °C to + 125 °C, + 25 °C ref.) (see table 1) • Rated power: to 1 W at + 125 °C • Resistance tolerance: to ± 0.005 % (50 ppm) • Load life stability: to ± 0.005 % at 70 °C, 2000 h or to ±0.015% at 70°C,10000 h (see table 4) • Resistance range: 10 Ω to 600 kΩ • 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) • Total accumulated change in resistance over life (EOL) < 0.05 % (or better with PMO) • Electrostatic discharge up to 25 000 V • Non-inductive, non-capacitive design • Rise time: 1 ns effectively no ringing • Current noise: 0.010 µVRMS/V of applied voltage (< - 40 dB) • Thermal EMF: 0.05 µV/°C typical • Voltage coefficient: < 0.1 ppm/V • Low inductance: < 0.08 µH typical • Thermal stabilization time < 1 s (nominal value achieved within 10 ppm of steady state value) • Pattern design minimizing hot spots • Terminal finish: lead (Pb)-free or tin/lead alloy • Matched sets are available per request (TCR tracking: to 0.5 ppm/°C) • Prototype quantities available in just 5 working days or sooner.
