Common Mode Chokes Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required mounting configurations and terminal types. Confirm that the 700 mA current rating aligns with the operational load requirements of the target circuit. Check for updated datasheet revisions to ensure all electrical parameters remain consistent with design specifications. Ensure procurement channels provide genuine Panasonic Electronic Components products to guarantee performance reliability.

Common Mode Chokes Selection Notes

Select this component when dual-line common mode noise attenuation is required in through-hole assemblies. The 8.2 mH inductance value offers significant impedance at lower frequencies, suitable for general-purpose EMI filtering. Consider the 574 mOhm DCR impact on voltage drop within the power or signal path. Evaluate space constraints for through-hole placement relative to other board components.

Common Mode Chokes Part Context

This component belongs to the ELF series of line filters manufactured by Panasonic Electronic Components. The series focuses on providing robust electromagnetic interference suppression for various electronic applications. The ELF-18D214 specifically addresses needs for dual-line filtering with moderate current handling capabilities, fitting into broader system designs where noise integrity is critical.

Common Mode Chokes Replacement Considerations

Consult official Panasonic documentation for verified substitute part numbers within the ELF series or compatible line filter families. Ensure replacement components match the 8.2 mH inductance and 700 mA current ratings. Verify that any alternative maintains the same through-hole package dimensions and pin configuration for direct board compatibility.
