Revision 03-Jul-02

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.
