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)
