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.
Model SMN offers low TCR (absolute and tracking),
excellent load life stability, tight tolerance (absolute and
match), excellent ratio stability, low thermal EMF, low current
noise and low voltage coefficient -
all in the same resistor.

The SMN Surface Mount Network is made up of 4
independent BMF resistors in a small standard molded
epoxy package with 50 MIL lead pitch (JEDEC MS-012
package).
The electrical specification of this integrated construction
offers improved performance and better real estate utilization
over discrete resistors and matched sets. The resistor may
be used independently or as divider pairs.
Our Application Engineering Department is available to
advise and make recommendations. For non-standard
technical requirements and special applications, please
