Common Mode Chokes Procurement Notes

Verify the specific revision status, as production has been transferred to Singapore with documented discontinuation notices for older batches. Confirm RoHS compliance requirements against the manufacturing date code, as legacy stock may not meet current environmental standards. Cross-reference the exact datasheet version to ensure compatibility with current supply chain protocols.

Common Mode Chokes Selection Notes

Select this component when a robust through-hole solution is required for dual-line AC filtering at 2.7A. Consider the physical dimensions and lead spacing for PCB layout constraints. Evaluate thermal management needs based on the continuous current rating and ambient operating conditions within the target enclosure.

Common Mode Chokes Part Context

This part belongs to Panasonic's ELF-xxN series, which includes variants like ELF-20N030A and ELF-21N024A. These components share similar form factors but differ in current ratings and impedance characteristics. The series is widely used in general-purpose power line filtering across various electronics sectors.

Common Mode Chokes Replacement Considerations

Consult official replacement lists for ELF-xxN series updates. Verify pinout compatibility and electrical specifications before substituting with other manufacturers' common mode chokes.
