Current Sensors Procurement Notes

Verify the specific suffix TU indicates tube packaging versus RE or SP variants when sourcing. Confirm the 30A rating aligns with system requirements. Ensure the 8-SOIC footprint matches PCB design constraints. Check AEC-Q100 compliance if automotive grade is mandatory. Validate supply voltage range compatibility with target circuitry.

Current Sensors Selection Notes

Select this model for applications requiring isolated current sensing with minimal external components. The ratiometric output simplifies interface with microcontrollers using the same supply rail. Consider the 300 kHz bandwidth for high-frequency switching applications. The integrated design reduces board space compared to discrete solutions. Verify thermal management needs given the SOIC package limitations.
