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
Temperature Coefficient of Resistance (TCR):
Any value at any tolerance available within resistance range
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. By taking advantage of the overall stability and reliability of Vishay 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.
