Common Mode Chokes Procurement Notes

Verify the specific suffix 'SM' confirms the surface mount variant when sourcing. Confirm the 1.8 mH inductance value aligns with circuit requirements. Ensure the 1.9 A current rating meets peak load conditions. Check for RoHS compliance status if required by project specifications.

Common Mode Chokes Selection Notes

Select this component where high current filtering is necessary in a compact form factor. The 80 mOhm DCR minimizes voltage drop across the line. Consider thermal management capabilities given the 1.9 A rating. Evaluate footprint compatibility with existing PCB layouts before finalizing the design.
