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 analog applications.
BMF technology allows to produce customer oriented
products designed to satisfy challenging and specific
technical requirements.
One of the important parameters influencing stability is the
Temperature Coefficient of Resistance (TCR). Although the
TCR of Foil resistors is considered extremely low, this
characteristic has been further refined over the years.
The VFCP Series utilizes ultra precision Bulk Metal
Z-Foil
(BMZF).
The new Z-Foil technology provides a significant reduction of
the resistive element sensitivity to changes of temperature
due to ambient temperature variations (TCR) and to self
heating when power is applied (power coefficient).
The Z-Foil technology provides inherently an extremely low
and predictable Temperature Coefficient of Resistance
(TCR), a remarkably improved load life stability, low noise
and availability of tight tolerance.
The Flip Chip configuration provides a significant PCB space
saving of more than 35 % vs. the surface mount chip with
wrap-around terminations. The VFCP is available in any
value within the specified resistance range.
Our Application Engineering Department is available to
advise and make recommendations for non-standard
technical requirements and special applications, please
