INTRODUCTION
Z-foil based filled, hermetically sealed HZ-series resistors represent industry breakthrough. hermetic sealing eliminates ingress moisture oxygen, while acts thermal conductor, thus eliminating long term degradation elements unsealed resistors, while same time allowing device accept short periods overload without degradation. Z-foil technology provides significant reduction resistive components sensitivity ambient temperature variations (TCR) applied power changes (PCR). When combined with hermetic sealing filling, H-series resistors become most precise stable resistors available. With accuracies 0.001 resistance range from long term shelf life less than ppm, these devices virtually secondary standards that carried sets daily periodic calibration factory measurement equipment. series also available with laboratory metrology level precision long term stability with additional in-house oriented process such special plotting, mounted chip stabilization, thermal shock bake prior sealing, combined thermal shock power conditioning finished product, thermal power conditioning, component linearity test.
