Vishay Foil Resistors

INTRODUCTION

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.

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.

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.

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).

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.

Our application engineering department is available to

advise and make recommendations. For non-standard

technical requirements and special applications. Please
