Vishay Foil Resistors
High Precision Foil Resistor with TCR of ± 2.0 ppm/°C,
Tolerance of ± 0.005 % and Load Life Stability of ± 0.005 %
INTRODUCTION
Bulk Metal^® Foil (BMF) technology outperforms all other
resistor technologies available today for applications that
require high precision and high stability.
This technology has been pioneered and developed by
Vishay Foil Resistors (VFR), and products based on this
technology are the most suitable for a wide range of
applications. BMF technology allows the production of
customer-oriented products, designed to satisfy specific
challenging technical requirements.
The S series of BMF resistors 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 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. The standard design of
these resistors provides a unique combination of
characteristics found in no other single resistor.
VFR's application engineering department is available to
advise and to make recommendations. For non-standard
technical requirements and special applications, please
