Common Mode Chokes Procurement Notes

Verify the specific impedance value against official datasheets, as sources vary between 60 mOhms DCR and 10.5 kilo-ohm impedance. Confirm RoHS compliance status and package type directly with the manufacturer or authorized distributors to ensure alignment with project requirements.

Common Mode Chokes Selection Notes

Select this component for applications requiring 220 uH common mode inductance with low DC resistance. Ensure the operating current does not exceed the rated limit. Verify physical dimensions and mounting style compatibility with the target PCB layout before finalizing the design.

Common Mode Chokes Part Context

This part belongs to the P0XXX SMT Toroid Common Mode Choke Series from Pulse Electronics. The series offers various inductance values and current ratings for different EMI filtering needs. The P0421NLT specifically targets circuits needing moderate inductance with low insertion loss.

Common Mode Chokes Replacement Considerations

Consult official substitution lists from Pulse Electronics for compatible alternatives. Verify that any substitute matches the 220 uH inductance, 60 mOhms DCR, and physical footprint requirements.
