IRC OARS3R010FLF Resistor - Metal Element, 0.01 Ohms, 3W
Upgrade your electronic designs with the high-performance surface mount current sense resistor from IRC/TT Electronics. Designed for precision and reliability, the OARS3R010FLF resistor offers excellent thermal management and electrical characteristics suitable for various high-current applications.
Product Features:
Surface mount current sense resistor series (OARS, OARS-XP & OARSZ)
Metal element construction for durability and stability
Resistance value: 0.01 Ohms (10 milliohms)
Power rating: 3W
Flexible leads to accommodate thermal expansion
Open air design minimizes PCB heating
Low Temperature Coefficient of Resistance (TCR): ±40ppm/°C
Element TCR: ±20ppm/°C
Zero-ohm jumper version available (65A)
Qualified to AEC-Q200 standards
RoHS compliant and Pb-free
Electrical & Physical Data:
Resistance
0.01 Ohms
Power Rating
3W
Resistance Tolerance
±5% (for specific part numbers)
Construction & Mounting:
Constructed with copper terminations welded to a resistance alloy strip, the resistor's value is adjusted via control of width and optional notch trimming. The zero-ohm jumper is formed from copper strip with a Pb-free finish of 96% Sn / 4% Ag alloy. The design ensures minimal heat transfer into the PCB, keeping hot spots thermally distant from solder joints.
High precision applications benefit from Kelvin 4-terminal mounting, which provides accurate current sensing by separating current and voltage paths.
Packaging & Ordering:
Part Number (Europe): OARS1-R01JI (10 milliohms ±5%, Pb-free)
Part Number (Europe): OARS-1Z (zero-ohm jumper, Pb-free)
Part Number (USA): OARS1R010JLF (10 milliohms ±5%, Pb-free)
