OARS1R022FLF Description

Short technical summary and product information.

The TT Electronics/BI OARS1R022FLF is a surface mount current sense resistor from the OARS series. It features flexible leads that allow for thermal expansion and an open air design which minimizes PCB heating. This construction helps to keep the hot spot thermally distant from the solder joints.

Key electrical characteristics include a TCR (Temperature Coefficient of Resistance) of ±40ppm/°C, with the element TCR specified at ±20ppm/°C. The component is Pb-free and complies with EU Directive 2011/65/EU amended by (EU) 2015/863 (RoHS3).

The OARS format is designed to reduce undesirable heat delivery into the PCB, making it suitable for applications requiring precise current sensing. For high-precision applications, a Kelvin 4-terminal mounting method is recommended, where high current connections are made to larger pads and voltage sense connections to smaller central pads.

This resistor is suitable for various applications where accurate current monitoring is essential. Its construction allows for values down to 1mΩ, and it is AEC-Q200 qualified.
