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
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
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.
