POWER SOLUTION – WILLOW TECHNOLOGIES LTD Lead Free 2W 3W CURRENT DETECTORS RCS2(100A), RCS3(170A) Features and Applications Rating current 170A (0.1mohm-3W) and 100A (0.1mohm-2W) current detecting resistors for electric equipment. Excellent long-term stability and less than 50ppm/C TCR realized through the use of Ni alloy and fully fine welded structure. Simple 4-port Kelvin structure enables easy large current bus-bar installation. Current detection in precision power source, constant current source, industrial power conversion circuits, HEV of fuel cells, constant electronic load etc. Dimensions dia.G (mm) A B C D E F G dia.
