The 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.
