Bulk Metal® Foil Technology
Industrial Precision Resistors
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 pioneered and developed by
VISHAY, and products based on this technology are the most
suitable for a wide range of applications.
Generally Bulk Metal® Foil technology allows us to produce
customer orientated products designed to satisfy challenging
and specific technical requirements.
The VSR series of resistors is a low cost version of the well
established S-Series of resistors. These resistors are made
of foil elements so all of the inherent performance of foil is
retained. They do not however, have the same TCR or
tolerance ranges (see table 1 for details). These products find
a wide range of usage in high end stereo equipment and some
grades of test and measurement equipment.
Standoffs are dimensioned to provide a minimum lead
clearance of 0.010 inches between the resistor body and the
printed circuit board, when the standoffs are seated on the
board. This allows for proper cleaning after the soldering
process**.
Our Applications Engineering Department is prepared to
advise and to make recommendations for non standard
technical requirements and special applications, please
contact us.
