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).  
Voltage coefficient < 0.1 ppm/V  
Non-inductive: < 0.08 µH  
Terminal finishes available: lead (Pb)-free, tin/lead alloy  
Compliant to RoHS directive 2002/95/EC  
Matched sets are available per request  
Prototype quantities available in just 5 working days  
or sooner. For more information, please contact  
foil@vishay.com  
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.
