Bulk Metal
®
Foil 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 appilcations.
BMF technology allows us to produce Customer Orientated
products designed to satisfy challenging and specific technical
requirements.
Model SMN offers Extremely Low TCR (absolute and
Tracking), Excellent Load Life Stability, Tight tolerance
(absolute and Tracking), 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
Bulk Metal
®
Foil 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 resistors may be
used independently or as divider pairs.
