The hermetic sealing eliminates the ingress of moisture and oxygen, while the oil acts as a thermal conductor, thus eliminating long term degradat ion elements of unsealed resistors, while at the same time allowing the device to accept short periods of overload without degradation. Vishay’s Bulk Metal ® Foil outperforms all other resistor technologies available today for applications that require precision and stability. When combined with the hermetic sealing and oil filling, the H series resistors become one of the most precise and stable resistors available. With accuracies of 0.001 %, a resistance range from 5 Ω to 1.84 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.
