200 Datasheet, PDF (1/4 Pages) Vishay Siliconix – Bulk Metal® Foil Technology Conformally Coated Precision Current Sensing Resistors with TCR of 5 ppm/°C and values down to 5 mΩ

200 Series
Vishay Foil Resistors
Bulk Metal^® Foil Technology Conformally Coated
Precision Current Sensing Resistors
with TCR of 5 ppm/°C and values down to 5 mΩ
Any value available within resistance range
The VCS200 Series offers resistance values as low as 5 mΩ
and TCR’s as low as 5 ppm/°C with excellent long term
stability. The resistors are conformally coated. The 4 terminal
current sensing resistors can sustain 2 W continuously
without an appreciable change in resistance (0.5 %
maximum). The typical 50 % derating of the power
specification associated with other technologies is not
necessary.
Our Application Engineering Department is available to
advise and to make recommendations. For non-standard
technical requirements and special applications, please
