Do you believe the growing complexity of modern automotive electronics increases your long-term vehicle maintenance costs?
Bourns has introduced the CFG-A Series of metal-foil current-sense resistors designed specifically for automotive motor drives and power electronics. These components support modern 12- to 48-volt mild-hybrid vehicle architectures.
Why it matters
As vehicles transition to more complex hybrid systems, manufacturers require smaller, high-accuracy parts to monitor electrical loads. This series improves thermal current measurement within the increasingly crowded power modules found in newer vehicles.
The CFG-A Series resistors offer a resistance range of 1 to 30 mΩ and a maximum power rating of 2 W. They are available in 0508 and 0612 footprints to fit compact automotive electronics.
The players
Bourns
A global manufacturer of electronic components and sensors known for supplying precision parts used in automotive and industrial power management.
The details
The resistors utilize a metal-foil sensing element paired with a wide-terminal construction to handle thermal demands. This design is specifically engineered for automotive motor drives and power electronics that operate within 12- to 48-V mild-hybrid systems. These components are also AEC-Q200-compliant, indicating they have passed the rigorous stress testing required for electronic parts in harsh vehicle environments.
Timeline
Bourns announced the new product series on October 12, 2026.
The Home Front
The automotive industry is shifting toward 12- to 48-V mild-hybrid architectures to improve fuel efficiency and power support for modern electronic features. This component release aligns with that transition by providing the precise sensing hardware required for these advanced systems.
While these components are for automotive manufacturers, they represent the types of parts that help your hybrid vehicle's electrical system operate more efficiently. If you own a modern hybrid, ensure you follow the manufacturer's recommended maintenance schedule for the vehicle's electrical diagnostics.
The takeaway
Reliable thermal current measurement is critical as vehicle electronics become smaller and more powerful. Owners of 12- to 48-volt hybrid vehicles should keep a copy of their owner's manual in the glove box to better understand the diagnostic codes related to power management.
