Although the TCR of Bulk Metal(R) Foil resistors is considered extremely low, this characteristic has been further refined over the years. The VFCP Series utilizes ultra precision Bulk Metal(R) 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). IM PR O VE D 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. Our application engineering department is available to advise and make recommendations.
