VPR221Z (Z-Foil) Vishay Foil Resistors Ultra High Precision Z-Foil Power Resistor in TO-220 Configuration with TCR of ± 0.05 ppm/°C, PCR of 4 ppm/W and Load Life Stability of ± 0.005 % (50 ppm) FEATURES PR O DU CT  Temperature coefficient of resistance (TCR):   INTRODUCTION The Z-Foil Technology provides a significant reduction of the resistive component’s sensitivity to ambient temperature variations (TCR) and applied power changes (PCR). VPR221Z provides high rated power, excellent load life stability , low Temperature Coefficient (TCR) and low Power Coefficient (PCR) - all in one resistor. ± 0.05 ppm/°C Absolute TCR removes error due to temperature gradients. IM PR O VE D By taking advantage of the overall stability and reliability of Bulk Metal® Z-Foil resistors, designers can significantly reduce circuit errors and greatly improve overall circuit performances. Model VPR221Z is a 4 lead kelvin connected device. Our Application Engineering Department is available to advise and make recommendations.
