Reference micropotentiometer resistors for Ac-dc transfer and phase error measurements

The paper presents a range of radial thin-film resistors for use as references in micropotentiometer-type low-voltage ac-dc transfer standards and for the measurement of phase errors in precision resistors and current shunts. The measured ac-dc difference of new resistors with values above 3 Ω was within 10 μΩ/Ω at frequencies up to 1 MHz.
