ROHM recently announced the availability of shunt resistors, GMR50 series, delivering industry-leading 4W rated power (at electrode temperature Tk=90°C) in the compact 5.0mm×2.5mm (2010 type package) size. It is ideal for current detection in motors and power supply circuits used in automotive systems and industrial equipment.
This new series combines a revised electrode structure with optimized device design that improves heat dissipation to PCB where the resistor is mounted on. The result is a 39% smaller mounting area over conventional 4W rated products. In addition, this new series can sustain against overcurrent loads and deliver stable current detection accuracy even when unexpected loads exceeding the rated power are applied, contributing to improve reliability in system level (more info).
