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 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.
