Product Description

The EWWR0001J4R00T9 is a high-precision Current Sense Resistor featuring a 4mOhm Surface Mount Resistor design for accurate current measurement in compact PCB layouts. This device operates with a low resistance tolerance of ±1% and handles up to 3W power dissipation, suitable for voltage ranges up to 75V. It supports direct integration into power management circuits, motor control systems, or battery monitoring modules across automotive, industrial automation, and renewable energy applications. Operating within -55°C to +155°C, it ensures reliability in harsh environments. The component’s 2512 package size enables easy soldering and robust thermal performance. Key advantages include minimal temperature drift and low inductance, though its ultra-low resistance requires careful layout optimization to avoid parasitic effects. Battery capacity and screen size parameters are not applicable to this passive component.
