Current Sensors Procurement Notes

Verify the specific suffix SP21 against official LEM documentation to confirm pinout and packaging details. Ensure the supplier provides valid traceability for the HTFS series component. Cross-reference the manufacturer part number with authorized distributor lists to avoid counterfeit products. Confirm that the 5V supply requirement matches your system design constraints before finalizing the order.

Current Sensors Selection Notes

Select this model for applications requiring unidirectional current monitoring with PCB integration. The 22mm aperture accommodates conductors of corresponding diameter. Consider the 300A rating and 240kHz frequency limit for high-power switching environments. The closed-loop architecture ensures linearity across the operating temperature range.

Current Sensors Part Context

This component belongs to the LEM HTFS series of current transducers. It utilizes Hall effect sensing combined with flux gate technology to achieve accurate current measurement. The series is designed for robust performance in industrial settings where electrical isolation and thermal stability are critical requirements.

Current Sensors Replacement Considerations

Consult LEM official substitution guides for compatible alternatives within the HTFS or LA series. Verify that any substitute maintains the same 5V supply voltage and PCB footprint specifications.
