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.

Our Application Engineering Department is available to

advise and make recommendations. For non-standard

technical requirements and special applications, please
