Abstract
New quantum Hall array resistance standards (QHARS) with nominal values ranging from R/sub K//200 to 50R/sub K/ (i=2 plateau) have been developed. First results show that R/sub K//200 (/spl sim/129 /spl Omega/) and 16R/sub K//4130 (/spl sim/100 /spl Omega/) standards have Hall resistances which agree with their nominal values within 5 parts in 10/sup 9/ (1/spl sigma/) when supplied by currents up to 4 mA.
