In demanding industrial environments and harsh automotive applications, current sensors must overcome challenges such as electromagnetic interference, wide temperature ranges, and space constraints. The GO10-SME was designed precisely to address these challenges.
Accurate and stable, immune to environmental interference
Using differential sensing technology, the GO10-SME effectively rejects external magnetic field interference in noisy environments, maintaining excellent signal integrity even in severe electromagnetic conditions. Combined with proprietary stress and temperature compensation algorithms, the device achieves extremely high measurement accuracy across the entire wide operating temperature range – with a total error of only 1% over the full temperature range.
Fast response, timely control
A rapid response time of just 2 µs allows the GO10-SME to capture instantaneous current changes, providing reliable information for real-time control and system protection.
No hysteresis, excellent linearity
The unique open-loop Hall-effect design eliminates hysteresis, offering linearity as high as ±0.3% to ensure long-term consistency and repeatability of measurements.
Wide operating temperature range, suited for harsh conditions
With an operating temperature range of –40 °C to +125 °C and AEC-Q100 Grade 1 automotive qualification, the GO10-SME operates stably and reliably whether deployed in cold northern winters or inside a sealed enclosure with limited heat dissipation.

Thanks to its high accuracy, small package, and wide temperature capability, the GO10-SME is widely used across many industries:
Industrial automation – current sensing and feedback control in small motor drives and variable frequency drives, enabling more precise regulation and higher efficiency.
HVAC – current monitoring in inverter air conditioners, heat pumps, and other equipment, optimizing energy management and reducing power consumption.
Home appliances – power supply monitoring and fault detection in white goods such as washing machines, refrigerators, and microwave ovens, improving product reliability.
Renewable energy – current monitoring in solar inverters and DC/DC converters, providing accurate power management for photovoltaic systems.
Electric mobility – current sensing in e-bikes and on-board chargers, ensuring safe charging and precise battery management.
Automotive electronics – AEC-Q100 qualified, suitable for automotivegrade applications meeting stringent requirements.
