Vishay Foil Resistors
High Precision Bulk Metal
®
Foil Surface Mount Voltage Divider,
TCR Tracking of < 0.5 ppm/°C, Tolerance Match of 0.01 %
and Stability of ± 0.005 % (50 ppm)
FEATURES
Temperature coefficient of resistance (TCR):
absolute: (table 1)
± 0.05 ppm/°C (typical 0 °C to + 60 °C)
± 0.2 ppm/°C (typical - 55 °C to + 125 °C,
+ 25 °C ref.)
Tracking: (table 1)
0.1 ppm/°C typical
Resistance range: 1K to 10K
Foil resistors are not restricted to standard values/ ratios,
specific “as required” values/ratios may be supplied at no
extra cost or delivery (e.g 2K234/5K456)
Power coefficient tracking: ”R due to self heating”
5 ppm at rated power
Short time overload: ± 0.005 %
Tolerance: absolute and resistance ratio: to 0.01 %
Load life stability (0.1 W at 70 °C, 2000 h)
Absolute: 0.01 %
Ratio: 0.005 %
Electrostatic discharge (ESD) up to 25 000 V
Power rating at 70 °C: entire package: 0.1 W, divided
between the two resistors proportionally to their value
Non-inductive, non-capacitive design
Thermal EMF: 0.05 µV/°C typical
Current noise: < - 40 dB
Rise time: 1 ns effectively no ringing
Non inductive: < 0.08 µH
Voltage coefficient: < 0.1 ppm/V
Non hot spot design
Compliant to RoHS directive 2002/95/EC
Terminal finish: lead (Pb)-free or tin/lead alloy

INTRODUCTION
Bulk Metal
®
Z-Foil (BMZF) technology out-performs all other
resistor technologies available today for applications that
require ultra high precision and ultra high stability.
The new Z-Foil technology provides a significant reduction
of the resistive element’s sensitivity to changes of
temperature due to ambient temperature variations (TCR)
and to self heating when power is applied (power
coefficient).
Model
VFCD1505
offers low TCR (both absolute and
tracking), excellent load life stability, tight tolerance,
excellent ratio stability, low thermal EMF and low current
noise, all in one package. 0.05 ppm/°C absolute TCR
removes errors due to temperature gradients.
The
VFCD1505
surface mount divider provides tight
tolerance matching and TCR tracking between 2 resistors
simultaneously etched on one piece of foil on a common
substrate. The electrical specifications of this integrated
construction offers improved performances and better real
estate utilization over discrete resistors and matched pairs.
Our application engineering department is available to
advise and make recommendations for non-standard
technical requirements and special applications, please
