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.

Our application engineering department is available to

advise and to make recommendations. For non-standard
