VCS232Z (Z-Foil) Vishay Foil Resistors Document Number: 63095 For any questions, contact: foil@vishay.com www.vishay.com Revision: 16-Apr-07 1 Ultra High Precision Z-Foil Power Current Sensing Resistor with Absolute TCR of ± 0.05 ppm/°C , PCR of 5 ppm at Rated Power and Tolerance of ± 0.02 % IMPRO VE D PR ODUCT Any value at any tolerance available within resistance range INTRODUCTION VCS232Z is the industry’s first device to provide high rated power, excellent load life stability, and low TCR - all in one resistor. The Z-Foil Technology provides a significant reduction of the resistive component’s sensitiv ity to ambient temperature variations (TCR) and applied power changes (PCR). The latest developments in Fo il resistors technology have reduced the temperature coefficient of Resistance (TCR): ± 0.05 ppm/°C Absolute TCR removes error due to temperature gradients. By taking advantage of the overall stability and reliability of Vishay’s Bulk Metal ® Z-Foil resistors, designers can significantly reduce circuit errors and greatly improve overall circuit performances. Model VCS232Z is a 4 lead kelvin connected device. Our Application Engineering Department is available to advise and make recommendations.
