INTRODUCTION
Vishay Foil resistors are designed and manufactured to
eliminate the inter-parameter compromise inherent in all
other types of precision resistors. All important
characteristics - tolerance, long term and load stability,
temperature coefficient, noise, capacitance and inductance -
are optimum, approaching in total performance the
theoretical ideal, a straight wire.
Vishay has developed a new resistor concept, through the
use of a proprietary Bulk Metal
®
and new, ultrafine
photoetching techniques created by the company, so that the
conductor can be considered a flat wire. Because the metals
used are not drawn, wound or mistreated in any way during
the manufacturing process, Vishay resistors maintain all of
their design, physical and electrical characteristics. These
factors are both measureable and predictable before, during
and after manufacture.
Through the entire process, every step is carefully controlled
not only to keep the metal in its virgin state, but also to
eliminate the effects of any stresses that might be imposed
either during manufacture or use. The sub-assembled is
guarded from external stresses by a flexible shock-absorbing
insulation. In addition, the temperature coefficient of the
resistor is carefully controlled through compensating
techniques to eliminate the effect of different coefficients of
expansion for all materials used in the resistor.
Vishay resistors thus achieve maximum stability and near
zero temperature coefficient. This superior performance is
built-in for every unit, and does not rely on culling or other
artificial means for uniform excellence. As expected, this
unique process delivers a new state-of-the-art resistor with
unmatched stability and total performance.
All Vishay resistors are produced from Bulk Metal film
elements of known and controllable characteristics. These
elements are photoetched into a variety of resistive patterns
in such a way the resistance is adjustable to a tolerance as
low as 0.01 %.
Permanent contact is provided through flexible ribbon leads
welded to the resistive element, and then by wire leads
welded to these ribbons. Routine assembly of the
component to its circuit is assured while maintaining a
flexible, non-stressing connection to the element.
All Vishay resistors exhibit identical temperature coefficients
because all are made of the same alloy and are of identical
thickness. Thus, accurate “tracking” of one Vishay resistor to
another is assured. Because of this excellent tracking ability,
Vishay resistors are ideal for use in resistor networks where
accurate ratios must be maintained.
The entire assembly is built to eliminate or minimize the
effects of thermal and mechanical stresses.
Due to the unique performance of the Bulk Metal
®
foil
resistive elements, these resistors are very well adapted to
high reliability applications.

advise and to make recommendations. For non-standard
technical requirements and special applications, please
