Metal-Foil Current-Sense Resistors Built for Automotive and High-Rel Apps
Bourns’ CFG-A Series of wide-terminal, metal-foil current-sense resistors are rated up to 2 W and available in 0508 and 0612 footprints. Covering a resistance range of 1 to 30 mΩ, the CFG-A Series is AEC-Q200-compliant and designed for automotive power electronics, motor drives, and other high-reliability applications that require accurate, thermally stable current measurement.
Designed to support automotive electrification, spanning 12- to 48-V mild-hybrid architectures and beyond, the components meet higher current-sensing accuracy requirements within tight available board space.
They provide cost-effective solutions for applications where AEC-Q200-qualified passives are standard, and designers face growing pressure to manage thermal hotspots within compact ECUs and power modules without enlarging their PCB footprint.
The CFG-A Series addresses those demands directly through its metal-foil sensing element, wide-terminal construction, and automotive-grade qualification.

Lee is the author of the popular PowerBites series.
Lee Goldberg is a self-identified “Recovering Engineer,” Maker/Hacker, Green-Tech Maven, Aviator, Gadfly, and Geek Dad. He spent the first 18 years of his career helping design microprocessors, embedded systems, renewable energy applications, and the occasional interplanetary spacecraft. After trading his ‘scope and soldering iron for a keyboard and a second career as a tech journalist, he’s spent the next two decades at several print and online engineering publications.
Lee’s current focus is power electronics, especially the technologies involved with energy efficiency, energy management, and renewable energy. This dovetails with his coverage of sustainable technologies and various environmental and social issues within the engineering community that he began in 1996. Lee also covers 3D printers, open-source hardware, and other Maker/Hacker technologies.
Lee holds a BSEE in Electrical Engineering from Thomas Edison College, and participated in a colloquium on technology, society, and the environment at Goddard College’s Institute for Social Ecology. His book, “Green Electronics/Green Bottom Line - A Commonsense Guide To Environmentally Responsible Engineering and Management,” was published by Newnes Press.
Lee, his wife Catherine, and his daughter Anwyn currently reside in the outskirts of Princeton N.J., where they masquerade as a typical suburban family.
