Common Mode Chokes Procurement Notes

Verify the exact datasheet version and any Product Change Notifications (PCNs) prior to ordering, as manufacturing specifications may evolve. Confirm that the 1.55 A current rating and 6 mH inductance meet your circuit's thermal and impedance requirements. Ensure the through-hole footprint matches your PCB layout constraints. Check RoHS compliance status if required by your assembly standards.

Common Mode Chokes Selection Notes

Select this component when a high-impedance common mode choke is needed for power lines with currents up to 1.55 A. The 6 mH inductance provides significant attenuation for high-frequency noise. Consider the vertical mounting profile and unshielded nature during mechanical design. Compare against similar models like PA3747.405NL if lower current or different inductance values are acceptable for the application.

Common Mode Chokes Part Context

This part belongs to the PA3747 series of common mode chokes from Pulse Electronics Power. The series offers various inductance and current ratings tailored for power line filtering. The PA3747.605NL specifically targets applications requiring higher inductance than the .405 variant but handles less current than higher-rated counterparts. It is categorized under Inductors, Chokes & Coils.

Common Mode Chokes Replacement Considerations

The PA3747.405NL is a related model in the same series but differs in inductance (2.68 mH) and current rating (2.25 A). Verify if these differences suit your design before substituting. No other direct public substitutes are confirmed in the provided data.
