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
FEATURES
Temperature coefficient of resistance (TCR):
± 2 ppm/°C typical (- 55 °C to + 155 °C, ref. + 20 °C)
Resistance range: 80.6 to 120 k
Foil resistors are not restricted to standard values; specific
“as required” values can be supplied at no extra cost or
delivery (e.g. 1K2345 vs. 1K)
INTRODUCTION
Bulk Metal® Foil (BMF) technology outperforms all other
resistor technologies available today for applications that
require high precision and high stability.
Rated power: to 0.25 W at + 125 °C
Tolerance: ± 0.01 %
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.
Load life stability: to ± 0.005 % at 70 °C, 2000 h at rated
power
Models RS92N, RS92NA, and AN made from 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.
Current noise: < - 40 dB
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.
Low inductance: < 0.08 µH typical
Electrostatic discharge up to 25 000 V
Non inductive, non capacitive design
Rise time: 1 ns effectively no ringing
Thermal EMF: 0.05 µV/°C typical
Voltage coefficient: < 0.1 ppm/V
Non hot spot design
Terminal finish available: tin/lead alloy
Matched sets are available per request
(TCR Tracking: to 0.5 ppm/°C)
Metal®
RS92N, RS92NA, and AN resistors are
Vishay’s Bulk
the modern generation of precision resistors. The standard
design of these resistors provides a unique combination of
characteristics found in no other single resistor.
For better TCR and PCR performances please review the
RNC90Z and Z555 datasheets
Our Application Engineering Department is available to
advise and to make recommendations. For non-standard
technical requirements and special applications, please
