Product Description

The R3117K091A-TR resistor is a surface-mount (SMD) component from the R3117K series, designed for precision current sensing applications. This compact resistor features a low resistance value of 0.091 Ω (091A code) with a tolerance of ±1%, optimized for accurate current detection in circuits up to 2 W power rating. It operates within a wide temperature range of -55°C to +155°C and supports a voltage range of up to 75 V. Ideal for industrial automation, power supplies, and automotive systems, the device offers high stability with a low temperature coefficient (TCR) of ±300 ppm/°C. Its SMD structure enables direct integration into PCB designs, minimizing space requirements. While lacking built-in communication interfaces, its primary advantage lies in high-current sensing reliability. However, precise PCB layout is critical to mitigate thermal drift. Battery capacity and screen size are not applicable to this passive component.
