ROHM launches Industry’s Highest Rated Power Shunt Resistors in the 0508 Size

ROHM has recently developed wide terminal shunt resistors,LTR10L. They are optimized for a variety of applications in the automotive, industrial, and consumer sectors, while also strengthening its considerable lineup with two updated general-purpose MCR series shunt resistors(MCR10L and MCR18L). In recent years, high efficiency operation is required from the viewpoint of energy conservation – not only in battery-driven applications such as mobile devices and EVs, but in consumer and industrial equipment as well powered by electrical outlets. For high efficiency, it is important to accurately detect parameters such as current and voltage in order to operate devices optimally. This requires shunt resistors that combine high accuracy with high reliability current detection. At the same time, manufacturers of applications utilizing higher board densities are demanding even smaller shunt resistors. To meet these needs, the newLTR10Lseries delivers the industry's highest rated power and best-in-class temperature coefficient of resistance (TCR) in a compact 0508-size (0.5inch ×0.8inch) / 1220-size (1.25mm × 2.0mm) that contributes to both high reliability and greater miniaturization. Improving the resistive element material and applying terminal temperature deratingmethod allowedLTR10L to deliver an industry-leading 1Wrated power in the 0508-size - 88% smaller than existing pro...
