Common Mode Chokes Procurement Notes

Verify the specific datasheet version as RoHS compliance status may vary by production batch. Confirm pin pitch and lead form compatibility with your PCB layout before ordering. Ensure the operating current does not exceed the 3A rating to maintain performance integrity.

Common Mode Chokes Selection Notes

Select this component when through-hole assembly is required for robust mechanical connection. Consider the 3A current rating and 115°C temperature limit against your system's operational requirements. Verify that the vertical package dimensions fit within the designated enclosure space.

Common Mode Chokes Part Context

This part is part of Panasonic's N series of common mode chokes, designed for electromagnetic interference suppression. It serves as a passive component to filter out high-frequency noise from differential signals or power lines in various electronic applications.

Common Mode Chokes Replacement Considerations

Direct substitutes must match the 3A current rating, 4-pin vertical through-hole package, and similar impedance characteristics. Consult official Panasonic documentation for qualified alternative part numbers within the same series.
