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 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.
