Common Mode Chokes Procurement Notes

Verify component status as obsolete before procurement planning. Confirm RoHS compliance status from official datasheets as sources vary. Ensure through-hole footprint compatibility with existing PCB layouts. Check lead-free status requirements against project specifications. Validate electrical parameters against original design intent due to potential supply chain changes.

Common Mode Chokes Selection Notes

Select this component only if through-hole mounting is required for mechanical stability or high-current handling. Verify that the 1.6 A current rating meets the application's peak load requirements. Ensure the 180 mOhm DCR does not cause excessive voltage drop in the power path. Consider alternative surface-mount solutions if space constraints exist.

Common Mode Chokes Part Context

This component belongs to Panasonic's ELF series of common mode chokes. The series offers various current ratings and inductance values for power line filtering. The ELF-25C016A specifically targets applications requiring robust through-hole components for dual-line noise suppression. It serves as a passive EMI filter element in power supply circuits.

Common Mode Chokes Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, direct replacements may require redesigning the PCB layout.
