OARS1R022FLF Description

Short technical summary and product information.

The Welwyn Components OARS1R022FLF is a surface mount current sense resistor from the OARS series. It is designed for applications requiring precise current monitoring.

 

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

 

This resistor features an open air design which helps reduce PCB heating and keeps the hot spot thermally distant from solder joints. It is suitable for surface mounting and is qualified to AEC-Q200 standards. The construction involves copper terminations welded to a resistance alloy strip, with value adjustment achieved through width control and optional notch trimming.
