1 / 4 page Document Number: 63017 For any questions, contact: foil@vishay.com www.vishay.com Revision: 16-Jul-07 1 200 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 m Ω Any value available within resistance range The VCS200 Series offers resistance values as low as 5 m Ω 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 contact us.
