INTRODUCTION

Vishay VSMP2018 ultra high precision Bulk Metal

Z-Foil

resistor is the result of a new concept in resistors

manufacturing: A proprietary Bulk Metal Foil of known and

controllable properties is applied to a special ceramic

substrate. A resistive pattern is then photoetched by an

ultra-fine technique developed by Vishay.

This process results in a resistor element that combines the

all important characteristics of low temperature coefficient

(TCR), long-term stability, ESD immunity, tight tolerance,

non-inductance, low capacitance and low noise.

These characteristics are optimum, approaching in total

performance the theoretical ideal, a straight wire.

The behavior of Vishay resistors under load is characterized

by a very small initial resistance change which occurs within

the first 500 h of the test. Only insignificant resistance

changes are observed upon continuation of the test, and no

signs of wear out appear even at full load over several

thousands hours.

The VSMP has a full wraparound termination which ensures

safe handling during the manufacturing process, as well as

providing stability during multiple thermal cyclings.

Our application engineering department is available to

advise and make recommendations. For non-standard

technical requirements and special applications, please
