SMNZ (Z-Foil)
Vishay Foil Resistors
Ultra High Precision Z-Foil Surface Mount 4 Resistor Network
Dual-In-Line Package with TCR Tracking of 0.1 ppm/°C, PCR
Tracking of 5 ppm at Rated Power, and Tolerance Match of 0.01 %
Any value and any ratio available within resistance range
INTRODUCTION
The Z-Foil Technology provides a significant reduction of the
resistive components’ sensitivity to ambient temperature
variations (TCR) and applied power changes (PCR).
0.05 ppm/°C Absolute TCR removes errors due to
temperature gradients.
Model SMNZ offers extremely low TCR (absolute and
tracking), excellent load life stability, tight tolerance (absolute
and matching), excellent ratio stability, low current noise, low
voltage coefficient and non sensitivity to ESD - all in the
same resistor.
The SMNZ Surface Mount Network is made up of 4
independent Bulk Metal® Z-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 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
