Current Sensors Procurement Notes

Verify the specific suffix 'CR' corresponds to the tape and reel packaging configuration when ordering. Confirm that the 10mV/mT sensitivity variant matches the system design requirements for the intended magnetic field range. Ensure the 4-SSIP package dimensions align with the target PCB footprint and mechanical assembly constraints. Check for AEC-Q100 qualification status if automotive grade compliance is required for the final product.

Current Sensors Selection Notes

Select this component when high-speed current sensing up to 250kHz is required alongside precise linear measurement. The bidirectional nature supports both positive and negative current flow monitoring. Consider the integrated diagnostics for system reliability. The traditional Hall approach requires an external magnetic core, which must be accounted for in the mechanical design phase to ensure proper flux coupling and isolation performance.
