Common Mode Chokes Procurement Notes

Verify the specific suffix (NLT vs NL) against the manufacturer's current datasheet to confirm availability and exact specifications. Note that some sources indicate the base model P0429 may be end-of-life; ensure the selected variant matches active production status and RoHS compliance requirements for your region before ordering.

Common Mode Chokes Selection Notes

Select this component when high current capacity and compact surface-mount form factor are required for power line filtering. The 810 µH inductance provides effective common mode noise attenuation. Ensure board space accommodates the 27.94 mm length and verify thermal management capabilities align with the 120°C maximum operating temperature limit.

Common Mode Chokes Part Context

This part belongs to the PO-xxx series of common mode chokes from Pulse Electronics. The series offers various inductor sizes and current ratings tailored for DC/DC converters. The P0429NL specifically addresses applications requiring robust current handling in a surface-mount configuration.

Common Mode Chokes Replacement Considerations

Check for direct substitutes within the PO-xxx series or equivalent SMD common mode chokes from other manufacturers offering similar 810 µH inductance and 9.7 A current ratings. Verify pin compatibility and physical dimensions to ensure mechanical fit.
