High Precision Bulk Metal® Foil Surface Mount Voltage Divider,
TCR Tracking of < 0.5 ppm/°C, Tolerance Match of 0.01 %
and Stability of ± 0.005 % (50 ppm)
Any value at any ratio available within resistance range
INTRODUCTION
Bulk Metal® Foil Technology out-performs all other resistor
technologies available today for applications that require High
Precision and High Stability.
This technology has been invented, patented and pioneered
by Vishay. Products based on this technology are the most
suitable for a wide range of appilcations.
BMF technology allows to produce customer oriented
products designed to satisfy challenging and specific
technical requirements. Model DSM offers Low TCR (both
absolute and tracking), Excellent Load Life Stability, Tight
tolerance, Excellent Ratio Stability, and Low Current Noise,
all in one package.
The DSM surface mount divider provides a matched pair of
Bulk Metal® Foil Resistors in a small epoxy molded package.
The electrical specification of this integrated construction
offers improved performance and better real estate utilization
over discrete resistors and matched pairs.
Our Application Engineering Department is available to
advise and make recommendations. For non-standard
technical requirements and special applications, please
contact us.
