0.05 ppm/°C (0 °C to 60 °C)
Pb-free
Available
• Power coefficient “ΔR due to self heating”:
5 ppm at rated power
• Tolerance: to 0.001 % (10 ppm)
RoHS*
COMPLIANT
• Load life stability:
0.002 % maximum ΔR (60 °C for
Any value available within resistance range
2000 h at 0.1 W per chip)
• Electrostatic discharge (ESD) > 25 000 V
INTRODUCTION
• Resistance range: 10 Ω to 150 kΩ (higher or lower values
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.
of resistance available)
• Power rating: 0.3 W at + 25 °C
• Shelf life stability: 2 ppm for at least ꢀ0 years
• Non inductive, non capacitive design
• Non hot spot design
• Rise time: 1.0 ns without ringing
• Current noise: < - 40 dB
• Thermal EMF: 0.05 µV/°C typical
• Voltage coefficient: < 0.1 ppm/V
• Non inductive: < 0.08 µH
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.
• Terminal finishes available: lead (Pb)-free
tin/lead alloy
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.
• Impervious to harmful environments - oil filled

APPLICATIONS
• Metrology
• Laboratory
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.
