Characterization of 100-$\Omega$ Metal Foil Standard Resistors

Aiming to produce devices for use in high-precision measurements (e.g., as a working standard for calibration work in National Meteorology Institutes), we develop standard resistors with a four-terminal-pair design using high-stability 100-<formula formulatype="inline"><tex Notation="TeX">$\Omega$</tex></formula> metal-foil resistor components. The current and frequency dependence of the resistance and phase angle have been characterized. Below a current of 5 mA, no current dependence is found within the uncertainty range, and no frequency dependence within the expanded measurement uncertainty range of around 2.5 <formula formulatype="inline"> <tex Notation="TeX">$\mu\Omega/\Omega$</tex></formula> is found below a frequency of 2 kHz. From the phase-angle measurement results, the time constant of the resistor is estimated to be less than 3.7 ns.
