The VFC1206 is a surface mountable flip chip resistor that
utilizes Ultra Precision Bulk Metal
from other Vishay Bulk Metal
as much as it is installed with the foil side facing the PCB
providing better power handling capabilities. The Foil
element is isolated from the PCB by a protective overcoating.
This overcoating plus the overall product design isolates the
resistor from handling and installation stresses.
The temperature coefficient of resistance (TCR) curve shown
below compares the new revolutionary “Z” Foil with its TCR of
< 0.5ppm/°C to the original Vishay “C” Foil. The Bulk Metal
Foil characteristics of excellent long term stability, low noise
and availability of tight tolerance are maintained in this Flip
Chip configuration. The VFC1206 is available in any value
within the specified resistance range. The flip chip configuration
is more economical for high volume, anolog applications where
high precision is required.
