Vishay Foil Resistors
High Precision Surface Mount 4 Resistor Network
Dual-In-Line Package with TCR Tracking ≤ 0.5 ppm/°C,
Tolerance Match of 0.01 % and Ratio Stability of 0.005 %
UCT Any value and any ratio available within resistance range
INTRODUCTION
D _{Bulk Metal® Foil (BMF) Technology outperforms all other}
resistor technologies available today for applications that
require High Precision and High Stability.
O _{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.
R _{BMF technology allows us to produce Customer Orientated}
products designed to satisfy challenging and specific
technical requirements.
P _{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.
D _{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
E _package).
The electrical specification of this integrated construction
V ^{offers improved performance and better real estate utilization}
over discrete resistors and matched sets. The resistor may
be used independently or as divider pairs.
O ^{Our Application Engineering Department is available to}
advise and make recommendations. For non-standard
technical requirements and special applications, please
