INTRODUCTION

The Z-Foil based oil filled, hermetically sealed HZ Series

resistors represent an industry breakthrough. The hermetic

sealing eliminates the ingress of moisture and oxygen, while

the oil acts as a thermal conductor, thus eliminating

long-term degradation elements of unsealed resistors, while

at the same time allowing the device to accept short periods

of overload without degradation.

The Z-Foil technology provides a significant reduction of the

resistive components, sensitivity to ambient temperature

variations (TCR) and applied power changes (PCR). When

combined with the hermetic sealing and oil filling, the

HZ Series resistors become

the most precise and stable

resistors available.

They are used as the most precise

secondary standards for ultra precision metrology.

With accuracies of ± 0.001 % (10 ppm) and a resistance

range from 5



to 1.1 M and long term shelf life of less than

2 ppm, these devices are virtually secondary standards that

can be carried in sets for daily or periodic calibration of

factory measurement equipment.

The HZ Series is available with laboratory and metrology

level precision and long-term stability with additional

in-house oriented processes such as: chip stabilization,

special TCR plotting, additional treatments for ultra

stability and special post manufacturing operations

(PMO). (Please refer to the last page)
