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 %
Any value at any tolerance available within resistance range
INTRODUCTION
The H ries resistors are oil-filled, hermetically aled ultra precision resistors.
The hermetic aling eliminates the ingress of moisture and oxygen, while the oil acts as a thermal conductor, thus eliminating long term degradation elements of unaled 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 aling and oil filling, the H ries resistors become one of the most preci and stable resistors available .
With accuracies of 0.001 %, a resistance range from 5 Ωto 1.84 M Ω, and long term shelf life of less than 2 ppm,the devices are virtually condary standards that can be carried in ts for daily or periodic calibration of factory measurement equipment.
