Common Mode Chokes Procurement Notes

Verify the specific ordering suffix and RoHS compliance status before procurement, as lead-free availability may vary by production batch. Confirm that the through-hole package dimensions match the target PCB footprint. Ensure the 2.4 A current rating meets the application's peak load requirements without saturation.

Common Mode Chokes Selection Notes

Select this component when a 1.5 mH inductance value is required for common mode interference mitigation. The 2.4 A current rating suits moderate power applications. Consider the 250 V AC rating for line-side filtering tasks. Evaluate the 76 mOhm DC resistance impact on system efficiency.
