Measurements of temperature cofficient of standard resistors for selection of transfer standards

摘要

Temperature coefficients of 54 standard resistors with nominal value of 1Ω, 10Ω, 100Ω, 1kΩ, and 10kΩ were measured at the temperature range 23±2℃ with temperature increment of 1℃. The measured resistance-temperature data are reported. Two 1Ω resistors, three 10Ω resistors, and two 10kΩ showed resistance changes smaller that 1 x 10~-8/10mK at the neighbor of 23℃, and these resistors are selected as the candidates to be used as transfer standards.
