Overview
The OARS1R010FTR-LF is a 10 milliohm current sense resistor from TT Electronics designed with a unique open-air, elevated metal strip architecture. This 2W rated surface-mount component provides high precision current monitoring with a low 40ppm/C temperature coefficient and 1 percent tolerance. Its design allows for superior heat dissipation and minimizes thermal stress on the PCB solder joints.
Why Choose This Part
The elevated metal element design reduces the heat transferred to the PCB, allowing the resistor to operate at a 2W power rating within a compact footprint. A low temperature coefficient of 40ppm/C ensures measurement stability across its wide -55C to +160C operating temperature range.
Applications
DC-DC Converter Feedback
Used as a shunt resistor in the feedback loop of high-efficiency power converters to monitor output current.
Battery Management Systems
Facilitates accurate state-of-charge calculations by measuring charge and discharge currents in multi-cell battery packs.
Motor Drive Protection
Provides real-time phase current sensing for overcurrent protection and torque control in BLDC or stepper motor drivers.
