• The 1 Ohm (1R0) 1206 SMD Resistor is a precision low-value resistor engineered for accurate current measurement and control in modern electronic designs. With tight ±1% tolerance and 1/4W power rating, it excels as a current-sense/shunt resistor in power management circuits, battery charging systems, motor drivers, LED drivers, DC-DC converters, over-current protection, and any application requiring precise current monitoring with minimal voltage drop. It is also widely used for current limiting in LED strings, low-resistance dropping in power supplies, and general low-ohm applications where accuracy and stability are critical.
• Thick film technology ensures low temperature coefficient of resistance (TCR), excellent pulse handling, low inductance, minimal self-heating drift, and strong long-term stability against humidity, thermal cycling, and aging effects—providing dependable performance in power electronics, automotive modules, industrial controls, consumer devices, and IoT/sensor nodes.
• The larger 1206 footprint (compared to 0805) delivers improved power dissipation and thermal performance while remaining compact enough for dense PCB layouts, making it suitable for both automated high-volume SMT production and manual assembly/repair.
• Fully RoHS compliant and manufactured under strict quality controls, this resistor is a trusted, high-accuracy low-value component that engineers rely on for precise current sensing and reliable operation in demanding low-resistance applications.
