Current Sensors Procurement Notes

Verify the specific suffix DR indicates tape and reel packaging when sourcing components. Confirm that the manufacturer is Allegro MicroSystems and not a third-party distributor claiming original status. Ensure the part number matches the exact 30A rating variant rather than other sensitivities in the family. Check RoHS compliance status as per the latest datasheet revision. Validate the 16-SOIC package dimensions against your PCB footprint requirements before finalizing procurement orders.

Current Sensors Selection Notes

Select this component when a 30A unidirectional current sensing solution is required with high bandwidth up to 1MHz. The 200mV/A sensitivity provides a clear signal interface for standard ADCs. Consider the 16-SOIC package size for board space constraints. The wide operating temperature range suits harsh industrial environments. Ensure the application does not require bidirectional sensing, as this model is strictly unidirectional.

Current Sensors Part Context

This part belongs to the XtremeSense Crocus series, which integrates advanced magnetoresistive sensors with signal conditioning. The series is designed for robust performance in noisy electromagnetic environments. The CT432 base model family includes various current ratings and sensitivity options. This specific variant targets high-current applications requiring precise linear measurement.

Current Sensors Replacement Considerations

The CT432-HSWF20DR is a parameter-equivalent alternative with a 20A rating. Verify if the lower current limit meets system requirements. No direct cross-model substitutes are officially confirmed for identical 30A specifications.
