For more information, please contact foil@vishay.com 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 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.
