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, 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 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.
Vishay’s Bulk Metal® RS92N, RS92NA, and AN 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

FIGURE 1 - STANDARD IMPRINTING AND DIMENSIONS
Note
1. The standoffs shall be so located as to give a lead clearance of 0.010" minimum between the resistor body and the printed circuit board
when the standoffs are seated on the printed circuit board. This is to allow for proper cleaning of flux and other contaminants from the unit
after all soldering processes.
