H Series Vishay Foil Resistors New Generation of Secondary Standards Hermetically Sealed High Precision Bulk Metal® Foil Technology Resistors with TCR of ± 2 ppm/°C, Tolerance of ± 0.001 % and Load Life Stability of ± 0.005 % (Metrology, Laboratory, Instrumentation, Industrial) FEATURES The H series resistors are oil-filled, hermetically sealed ultra precision resistors and are used as secondary standards for metrology applications. The hermetic sealing eliminates the ingress of moisture and oxygen, while the oil acts as a thermal conductor, thus eliminating the long-term degradation 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 the most precise and stable resistors available. With accuracies of 0.001 %, a resistance range from 5 Ω to 1.84 MΩ, 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 H 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).

Can be reduced through in-house oriented processes POST MANUFACTURING OPERATIONS OR PMO FOR IMPROVED END OF LIFE Many analog applications can include requirements for performance under conditions of stress beyond the normal and over extended periods of time. This calls for more than just selecting a standard device and applying it to a circuit. The standard device may turn out to be all that is needed but an analysis of the projected service conditions should be made and it may well dictate a routine of stabilization known as post manufacturing operations or PMO. The PMO operations that will be discussed are only applicable to Bulk Metal Foil resistors. They stabilize Bulk Metal Foil resistors while they are harmful to other types. Short time overload, Document Number: 63006 Revision: 23-Mar-10 accelerated load life, and temperature cycling are the three PMO exercises that do the most to remove the anomalies down the road. Vishay Bulk Metal Foil resistors are inherently stable as manufactured. These PMO exercises are only of value on Bulk Metal Foil resistors and they improve the performance by amounts that are small but significant when compared to the very tight tolerances. Users are encouraged to contact Vishay Foil applications engineering for assistance in choosing the PMO operations that are right for their application.
