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 sensitiv ity to ambient temperature variations (TCR) and applied power changes (PCR). When combined with the hermetic sealing and oil filling, the H-series resistors become the most prec ise and stable resistors available. With accuracies of ± 0.001 % and a resistance range from 5 Ω to 1.1 M Ω 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 VHA series is also available with laboratory and metrology level precision an d long term stability with additional in-house orient ed process such as: special TCR plotting, mounted chip stabilization, thermal shock and bake prior to sealing, co mbined thermal shock and power conditioning on finished product, thermal and power conditioning, component linearity test.
