One of the most important parameters influencing stability is
the Temperature Coefficient of Resistance (TCR). Although
the TCR of Bulk Metal® 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.
The Z-Foil technology provides a significant reduction to the
resistive element’s sensitivity to ambient temperature
variations (TCR) and to self heating when power is applied
(power coefficient).
•
• Any value available within resistance range (e.g. 1K2345)
• Prototype samples available from 48 hours. For more
information, please contact foil@vishay.com
Along with the inherently low PCR and TCR, Z-Foil
technology also provides remarkably improved load life
stablility, low noise and availability of tight tolerance.

The Flip Chip configuration provides a substantial PCB
space saving of more than 35 % vs. a surface mount chip
with wraparound terminations. The VFCP is available in any
value within the specified resistance range.
