PSR400ITQFH1L00

ROHM announces the development of high-power, ultra-low-ohmic shunt resistors ideal for current detection in applications with increased power requirements, such as automotive systems and industrial equipment. The PSR series includes PSR400, which is rated at 4 W, and PSR500, guaranteed up to 5 W. Resistors in current detection applications are typically used to detect overcurrent conditions or remaining battery level. Although current-sense resistors have been widely-adopted in the automotive and industrial sectors, the recent trend towards greater sophistication and computerization has increased current requirements, leading to a need for high-power components. This includes a demand for high-accuracy resistors with superior temperature coefficient of resistance (TCR) for stable operation in extreme temperature environments, and that feature ultra-low-resistance values in order to minimize power consumption.
