Explore the engineering prowess of the ULH F Seriesโ€”precision metal-clad resistors with UL approval, designed for current sensing with high-power precision. Mirroring the attributes of the IRH F Series, the ULH F models excel in a versatile range from 30A to 500A rated current and precise resistance values spanning 0.2mฮฉ to 3.333mฮฉ. Tolerances of ยฑ0.1%, ยฑ0.5%, or ยฑ1% provide customization for specific engineering needs. With an ultra-low TCR of 15 or 30 ppm/ยฐC, these resistors maintain stability across temperature variations. Ideal for automotive, precision current sensing, constant current sources, industrial power conversion circuits, HEVs, and fuel cells. The ULH F Series stands as a UL-approved solution for diverse engineering challenges. Learn more at www.raraohm.com.
