INTRODUCTION
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). (Please refer to the last page)
