Vishay Foil Resistors

High Precision Foil Resistor with TCR of ± 2.0 ppm/°C,

Tolerance of ± 0.01 % and Load Life Stability

of ± 0.005 % CECC Qualified

INTRODUCTION

resistor technologies available today for applications that

require high precision and high stability.

This technology has been pioneered and developed by

VISHAY, and products based on this technology are the

most suitable for a wide range of applications. BMF

technology allows us to produce customer orientated

products, designed to satisfy challenging and specific

technical requirements.

Models RS92N, RS92NA, and AN made from Vishay BMF

offers low TCR, excellent load life stability, tight tolerance,

fast response time, low current noise, low thermal EMF and

low voltage coefficient, all in one resistor.

The RS92N, RS92NA, and AN are virtually insensitive to

destabillizing factors. The resistor element is a solid alloy

that displays the desirable bulk properties of its parent

material, thus it is inherently stable and noise free.

the modern generation of precision resistors. The standard

design of these resistors provides a unique combination of

characteristics found in no other single resistor.

Our Application Engineering Department is available to

advise and to make recommendations. For non-standard

technical requirements and special applications, please
