Current Sense Transformers Procurement Notes

Verify the specific suffix 'NL' against the manufacturer's latest datasheet to confirm packaging and material specifications. Ensure compatibility with reflow soldering profiles defined in official documentation. Check RoHS compliance status and moisture sensitivity level requirements for your manufacturing process. Confirm that the 1:1:100 ratio meets your signal conditioning needs before ordering.

Current Sense Transformers Selection Notes

Select this component when a high isolation voltage and precise current replication are required in a small footprint. The 14.8 mH inductance supports stable operation at frequencies up to 500kHz. Consider the 1.15 milliohm primary resistance for low insertion loss. Ensure the PCB layout accommodates the 12.57mm length and 7.11mm height constraints.
