Vishay Foil Resistors
www.DataUShelettr4Ua.c-oHm igh Precision Hermetically Sealed Bulk Metal® Foil
Technology Resistor with Zero TCR and 0.005 % Tolerance
Any value available within resistance range
Vishay has achieved an essentially zero temperature
coefficient resistor in the VHP100 family. This oil filled
hermetically sealed device makes unique use of foil on
ceramic in such a way that self cancelling responses to
temperature are produced by combining equal and opposite
effects. This product is sold only in hermetic packages
because applications requiring this level of temperature
stability require humidity stability as well.
The value of the hermetic enclosure over the molded part is
in the long term performance. The hermetic sealing prevents
the ingress of moisture and oxygen, while the oil acts as a
thermal conductor.
WINDOW DEFINITION
The TCR of the VHP100 is so small that an additional
definition - window, has been introduced. The window
definition requires that the absolute resistance remain within
the stated window over the temperature range specified. The
resistance of the VHP100 resistor stays within a 60 ppm
window over the entire military temperature range of - 55 °C
to + 125 °C (Figures 1 and 3).
A window of 10 ppm is available for the laboratory instrument
range (+ 15 °C to + 45 °C); see Figure 4 - type VHP101.
TRACKING
Tracking of the VHP100 resistor is also vastly superior to
conventional precision resistors. Typical ± 5 ppm/°C
precision resistors have a worst-case tracking of 10 ppm/°C
(wirewounds) or a difference between resistors of 1000 ppm
(10 ppm/°C x 100 °C) when temperature changes from
+ 25 °C to + 125 °C. For a 3 ppm/°C tracking (Vishay S102C)
the difference will be 300 ppm (3 ppm/°C x 100 °C) for the
same temperature range. The VHP100 resistors will track to
60 ppm from - 55 °C to + 125 °C, a five-fold improvement
over the S102C resistor.
