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
IMPROVED PRODUCT
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).
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. For non-standard
technical requirements and special applications, please
contact us.
