Description

The VPR221Z 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/ 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. Our Application Engineering Department is available to advise and make recommendations. For non-standard technical requirements and special applications, please contact us.
