Current Sensors Procurement Notes

Verify the specific suffix (e.g., SP3) against official LEM documentation to ensure correct pinout and mechanical compatibility. Confirm that the ±1500A peak rating aligns with system requirements. Check for ISO 26262 compliance if safety-related application data is required. Ensure supply voltage matches the 4.75V–5.25V specification before integration.

Current Sensors Selection Notes

Select this model for applications requiring fast response times and high bandwidth in motor control. The S07 variant is optimized for installation directly within inverter modules. Consider the small footprint advantage for space-constrained designs. Evaluate the proportional output signal characteristics against your microcontroller or ADC input requirements for accurate signal conversion.
