300144Z, 300145Z (Z-Foil)
Vishay Foil Resistors
INTRODUCTION
Change in a metal’s resistivity occurs in two ways: by
changes in temperature (external and internal) and by
changes in mechanical strain.
Possibly you have become so accustomed (and inured) to a
slight instability or drift in your equipment that you no longer
regard the problem as a soluble. 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.
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.
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.
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.
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).
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.
Temperature Coefficient of Resistance (TCR)
Our application engineering department is available to
advise and make recommendations. For non-standard
technical requirements and special applications. Please
contact us.
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.
