You have learned to live with it. But have your customers? They are still waiting for a solution. And if you cannot provide one, someone else may. There are so many stability problems directly traceable to resistive devices that skimping on the quality of a few critical resistors, resistive networks may be counterproductive. Load Life Stability Load Life stability is the characteristics most relied upon to demonstrate resistor long term reliability. Many applications require a load life of between 2000 h to 10 000 h with limits on the amount of shift and the number of failure rate demonstration. The ultra high precision Z-Foil divider and network have the tightest allowable limits. Whether high reliable application or not, the load life stability of Foil resistors is unparalleled and long term serviceability is assured. With Bulk Metal® Foil resistors, only a minimal shift in resistance value will occur during its entire lifetime. Most of this shift takes place during the first few hundred hours of operation, and virtually no change is noted thereafter. Ratio Stability Resistors in dividers or networks form are called upon to maintain a track and match more than at ambient temperature and when they expose to stress factors before, during and after the assembly. Throughout the long service life of the equipment, the resistors around the op amplifier for example are required to track (to hold ratio) even though the dissipation in the feedback resistor is different than that in the sense resistor, causing on one to be at higher temperature than the other. This is called tracking under power for short term (power coefficient of resistance) or for a long term (load life stability). Temperature Coefficient of Resistance (TCR) The low temperature coefficient of resistors are achieved by the use of especially selected materials for the resistive and insulating members of the resistors which self-compensate the thermal coefficient of expansion.  Change in a metal’s resistivity occurs in two ways: by changes in temperature (external and internal) and by changes in mechanical strain. By developing resistor element materials whose resistances change positively when subjected to temperature increase, and negativity when subjected to compression, the Foil resistors achieved, in the temperature range - 55 °C to + 125 °C, a maximum absolute TCR of 5 ppm/°C for the classical Foil and maximum 2 ppm/°C for the Z-Foil technology. To achieve maximum optimum TC tracking between resistors, all factors that affect the TCR of each resistor must be uniform. Whatever their resistance range or wattage, all Foil resistors exhibit identical temperature coefficients as all are made of the same alloy and of identical physical and electrical characteristics. The only variable between these resistors is the pattern photoetched on the element, a process that does not alter alloy properties in any way. In resistors, all TCR and other electrical characteristics are inherent to the alloy, and are therefore uniform between individual resistors, as well as between batches, thus accurate “tracking” of one style resistor to another is assured (even if they differ in size and range). Data on TCR spread shown (fig. 4) illustrate the excellent tracking available with all Foil resistors. Because of this excellent tracking ability, resistors are ideal for use in resistor networks where accurate ratios must be maintained over a wide temperature range. This designed-in TCR uniformity contrasts sharply with the TCR tracking capability of wirewound and conventional metal film units. TCR characteristics between wirewounds of different resistance ranges and wattage are highly non-uniform, because (a) different wire diameters are used, (b) winding-induced stresses-which have a direct bearing on TCR. Conventional metal films units offer quite variable and often unpredictable TC tracking because composition, film thickness, and deposition techniques are varied to meet different resistance range and wattage requirements.
