INTRODUCTION
The Bulk Metal
®
Foil resistor is based on a special
thermo-metalic stress concept wherein a proprietary bulk
metal cold rolled foil is cemented to a ceramic substrate. It is
then photoetched into a resistive pattern. Then 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 performance.
The stability of a resistor depends primarily on its history of
exposures to temperature. Stability is affected by:
1. Reversible changes in the ambient temperature and heat
from adjacent components (defined by the Temperature
Coefficient of Resistance, or TCR)
2. Short-term steady-state self-heating (defined by Power
TCR or PCR)
3. Irreversible destabilizing shock of suddenly-applied
power
4. Long-term exposure to applied power (load-life stability)
5. 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 Foil Resistors’ 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 TCR of
± 0.05 ppm/°C nominal (instrument range: 0 °C to +60 °C),
± 0.2 ppm/°C nominal (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.
