INTRODUCTION
Bulk Metal
®
Foil (BMF) 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 applications.
BMF technology allows to produce customer oriented
products designed to satisfy challenging and specific
technical requirements.
The BMF provides inherently a low and predictable
Temperature Coefficient of Resistance (TCR) and excellent
load life stability for high precision analog applications.

Model VSM offers low TCR, excellent load life stability, tight
tolerance, excellent shelf life stability, low thermal EMF, low
current noise and low voltage coefficient, all in the same
resistor.
The VSM has a full wrap around termination which insures
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
