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.
