INTRODUCTION
The VCS301 and VCS302 offer precision resistors as low as
5 m with a temperature coefficient down to 3 ppm/°C
maximum and unmatched long term stability. The 4 terminal
current sensing resistors, when mounted on a heat sink, can
sustain 10 W continuously without an appreciable change in
resistance (0.15 % maximum). The typical 50 % power
derating specification associated with other technologies is
not necessary. A choice of lead configurations is available.
Our application engineering department is available to
advise and make recommendations. For non-standard
technical requirements and special applications, please
contact us.
FEATURES
Temperature coefficient of resistance (TCR):
down to ± 3 ppm/°C max. (see table 2)
Tolerance: to ± 0.5 % (see table 1)
Power rating (heat-sinked): 10 W
Load life stability: ± 0.02 % (200 ppm) at 25 °C,
2000 h at rated power
Resistance range: 0.005 to 0.25
Vishay Foil resistors are not restricted to standard values;
specific “as required” values can be supplied at no extra
cost or delivery (e.g. 0R123 vs. 0R1)
Non inductive, non capacitive design
Rise time: 1.0 ns effectively no ringing
Thermal EMF: 0.05 µV/°C typical
Voltage coefficient: < 0.1 ppm/V
Non inductive: 0.08 µH
Non hot spot design
Terminal finish: lead (Pb)-free or tin/lead alloy
Compliant to RoHS directive 2002/95/EC
Prototype quantities available in just 5 working days
or sooner. For more information, please contact
foil@vishaypg.com
For better performances, please contact application
engineering
Notes
1. Tighter tolerance is available - for more details contact application engineering
2. The lower of the two limitations (power or current) is decisive
3. Heatsink - aluminum (6" length x 4" width x 2" height x 0.04" thick)
* Pb containing materials are not RoHS compliant, exemptions may apply
