Common Mode Chokes Procurement Notes

Verify availability status carefully as this part is officially listed as discontinued by Panasonic Industry. Confirm that the specific pinout and dimensional tolerances match your existing PCB layout, particularly the recommended piercing plan and hole diameters. Ensure compatibility with your assembly process regarding the through-hole mounting style and terminal coating specifications before finalizing design decisions.

Common Mode Chokes Selection Notes

Select this component when designing single-phase AC line filters requiring common mode chokes with a 0.3 A current rating. The 142 uH inductance value is suitable for standard EMI suppression tasks. Consider the physical footprint of 22.7 mm by 15.0 mm during board space allocation. Verify that the 7.543 Ohm DCR meets your circuit's voltage drop requirements.

Common Mode Chokes Part Context

This component belongs to the Panasonic High N Series, specifically the Type 17N line filter family. It shares design characteristics with other parts in the series, such as the ELF-15N variants, but differs in specific electrical ratings and physical dimensions. The series is characterized by its use in single-phase EMI filtering applications with through-hole construction.

Common Mode Chokes Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. As the part is discontinued, alternative components must be sourced based on matching electrical specifications (inductance, current rating, DCR) and mechanical constraints without relying on direct cross-reference data from the manufacturer.
