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



to 150 k 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.
