VFCP Series (0805, 1206, 1506, 2010, 2512) (Z-Foil) Vishay Foil Resistors Ultra High Precision Z-Foil Flip Chip Resistor with TCR of ± 0.05 ppm/°C, 35 % Space Saving versus Wraparound Design and PCR of 5 ppm at Rated Power FEATURES PR O DU CT Any value at tolerance available within resistance range INTRODUCTION One of the most important parameters influencing stability is the Temperature Coefficient of Resistance (TCR). Although the TCR of Bulk Metal® Foil resistors is considered extremely low, this characteristic has been further refined over the years. The VFCP Series utilizes ultra precision Bulk Metal® 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.
