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).

Model VPR221SZ is a 4 lead kelvin connected surface

mount device which 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.

Our application engineering department is available to

advise and make recommendations. For non-standard

technical requirements and special applications, please
