INTRODUCTION

Many manufacturers and users of precision electronic

equipment suffer unnecessarily with unexplained instabilities

and drifts. They resign themselves to the need for constant

adjustments and troubleshooting which could in fact be

avoided.

Often the instability is traceable to a few “fixed” resistors

which are not fixed at all. If these resistors would only retain

their original values, there would be no need for costly

controls and other compensating circuitry.

The answer? A real precision and stable resistor.

Some precision resistors offer you tight tolerance at the

expense of poor load life stability (1000 h or more), thermal

stabilization and ESD sensitivity, others offer low TCR at the

expense of poor rise time.

Only Vishay Bulk Metal

set of top performance characteristics, including TCR as low

as 0.2 ppm/°C with the Z-foil technology, a combination that

will most often free your equipment from that tormenting bug.

Vishay now offers you the chance to make your own custom

bulk-metal resistors for breadboard, prototype, or even

production use.

ABOUT THE VISHAY BULK METAL FOIL

RESISTOR

Vishay low cost high precision Bulk Metal Foil resistors are

the result of an improved concept in resistor manufacturing:

a proprietary Bulk Metal Foil of known and controllable

properties is applied to a special ceramic substrate.

A resistive pattern is then photo-etched by an ultra-fine

technique developed by Vishay. This process results in

resistor element characteristics of low TCR, long term

stability, non inductive, excellent thermal stabilization, low

capacitance and low noise.

The Bulk Metal Foil is a special alloy chosen for its electrical

mechanical and thermal characteristics. It is set on the

substrate by a unique and proprietary process which does

not subject the resistor element to the metallurgical changes

that occur during the winding of wire, or during the

evaporative process used in other forms of resistor

manufacturing. Because the alloy in the Vishay resistor is not

drawn, wound, work hardened, or stressed in any way during

manufacturing process, the resistor maintains all of its

0.2 ppm/°C (military range) with the Z-foil technology

more than 10 000 h

rated power for Z-foil resistors

we can supply specific “as required” values at no extra cost

or delivery (e.g. 1K2345 vs. 1K)

critical for low resistive value in DC current/voltage

production process (100 %)

when designing a board: TCR, PCR, thermal EMF and

ESD. Vishay Foil resistors provide the best combination of
