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.
