The VFC1506 is a surface mountable flip chip resistor that
utilizes Ultra Precision Bulk Metal^® “Z” Foil. This product
differs from other Vishay Bulk Metal^® Foil surface mount
devices in 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 below
shows the new revolutionary “Z” Foil with its nominal TCR
of 0.5ppm/°C. 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
VFC1506 is available in any value within the specified
resistance range. The flip chip configuration is more
economical for high volume, analog applications where high
precision is required.

The TCR for values < 100Ω are influenced by the termination
composition and result in a deviation from this curve.
