High-power, ultra-low-ohmic shunt resistors of PSR series include 4 W PSR400 and 5 W PSR500. Due to precision welding, products support high power requirements and ensure measurement accuracy even in ultra-low-ohmic (0.2 mΩ) region. Use of high-performance alloy for resistive metal optimizes temperature coefficient of resistance. Typical uses include current detection (detecting overcurrent conditions or remaining battery level) in automotive systems and industrial equipment applications.
