INTRODUCTION
Vishay VSMP2018 ultra high precision Bulk Metal
®
Z-Foil
resistor is the result of a new concept in resistors
manufacturing: A proprietary Bulk Metal Foil of known and
controllable properties is applied to a special ceramic
substrate. A resistive pattern is then photoetched by an
ultra-fine technique developed by Vishay.
This process results in a resistor element that combines the
all important characteristics of low temperature coefficient
(TCR), long-term stability, ESD immunity, tight tolerance,
non-inductance, low capacitance and low noise.
These characteristics are optimum, approaching in total
performance the theoretical ideal, a straight wire.
The behavior of Vishay resistors under load is characterized
by a very small initial resistance change which occurs within
the first 500 h of the test. Only insignificant resistance
changes are observed upon continuation of the test, and no
signs of wear out appear even at full load over several
thousands hours.
The VSMP has a full wraparound termination which ensures
safe handling during the manufacturing process, as well as
providing stability during multiple thermal cyclings.
Our application engineering department is available to
advise and make recommendations. For non-standard
technical requirements and special applications, please
