Common Mode Chokes Procurement Notes

Verify the specific datasheet version and product change notifications prior to ordering, as manufacturing updates may occur. Confirm that the through-hole pin configuration matches the target PCB footprint dimensions. Ensure the 1.5 A current rating and thermal limits align with the system's operational requirements to prevent saturation or overheating during peak loads.

Common Mode Chokes Selection Notes

Select this component when high inductance is required for low-frequency noise attenuation in power circuits. The through-hole format is suitable for applications requiring robust mechanical stability. Compare the 1.5 A current limit against the circuit's maximum load to ensure adequate headroom. Consider the physical size constraints relative to other available common mode chokes in the series.

Common Mode Chokes Part Context

This part belongs to the PA3747 series of common mode chokes from Pulse Electronics. The series offers various inductance values tailored for different filtering needs. The PA3747.705NL specifically targets applications requiring higher inductance compared to lower-value variants like the PA3747.105NL, providing stronger attenuation characteristics for specific interference profiles.

Common Mode Chokes Replacement Considerations

The PA3747.405NL serves as a substitute with lower inductance (2.68 mH) but higher current capacity (2.25 A). Verify if the reduced inductance meets the noise suppression requirements. Other series members may offer different current ratings or package styles, requiring re-evaluation of thermal and spatial constraints.
