INTRODUCTION
•
•
Electrostatic discharge above 25 000 V
Non inductive, non capacitive design
Bulk Metal® Foil (BMF) technology outperforms all other
resistor technologies available today for applications that
require high precision and high stability.
• Rise time: 1 ns without ringing

•
Current noise: < - 40 dB
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.
Thermal EMF: 0.05 µV/°C typical
Voltage coefficient: < 0.1 ppm/V
Low inductance: < 0.08 µH typical
Non hot spot design
• Terminal finishes available: lead (Pb)-free
tin/lead alloy

•
Matched sets are available per request
(TCR Tracking: to 0.5 ppm/°C)
For better TCR and PCR performances please review the
Model S Series 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.

APPLICATIONS
• High precision amplifiers
The S Series is 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.
• Down-hole (high temperature)
• High precision instrumentation
• Medical and test equipment
• Industrial
• Audio (high end stereo equipment)
• EB applications (electron beam scanning and recording
equipment, electron microscopes)
• Military, airborne
Vishay’s Bulk Metal® S Series resistors are 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
