VHP203 (Z-Foil)
Vishay Foil Resistors
wHwwe.DramtaSeheteit4cUa.colmly Sealed Miniature Ultra High Precision Z-Foil Technology
Resistors with TCR of 0.05 ppm/°C, Tolerance of ± 0.001 % and
Load Life Stability of ± 0.005 %, Unaffected by Humidity
Any value available within resistance range
INTRODUCTION
The Z-foil based oil filled, hermetically sealed VHP203
resistor represents an industry breakthrough. The hermetic
sealing eliminates the ingress of moisture and oxygen, while
the oil acts as a thermal conductor, thus eliminating long term
degradation of elements of unsealed resistors, while at the
same time allowing the device to accept short periods of
overload without degradation.
The VHP203 is also available with laboratory and metrology
level precision and long term stability with additional inhouse
oriented process such as: special TCR plotting, chip
stabilitzation inhouse thermal shock and bake prior to
sealing, combined thermal shock and power conditioning on
finished product, thermal and power conditioning, CLT.
The Z-foil technology provides a significant reduction of the
resistive components sensitivity to ambient temperature
variations (TCR) and applied power changes (PCR). When
combined with the hermetic sealing and oil filling, the
VHP203 resistor become the most precise and stable
resistor available.
The value of the hermetic enclosure over the molded part is
in long term performance.
With accuracy of ± 0.001 % (10 ppm) and a resistance range
from 10 Ω to 150 kΩ and long term shelf life of less than
2 ppm, this device is virtually a secondary standard that can
be carried in sets for daily or periodic calibration of factory
measurement equipment.
