Common Mode Chokes Procurement Notes

Verify the specific datasheet version before procurement, as manufacturer notifications may indicate changes to physical dimensions or electrical characteristics. Confirm that the through-hole pin configuration matches the target footprint. Ensure the selected component meets the required thermal management standards for the intended operating environment.

Common Mode Chokes Selection Notes

Select this component when dual-line noise attenuation is required at 5 mH inductance with a 1.85 A current capacity. Consider the vertical form factor for assembly constraints and verify that the unshielded design does not interfere with adjacent sensitive components. Ensure the operating temperature range aligns with the system's environmental conditions.

Common Mode Chokes Part Context

This part belongs to Pulse Electronics' PA3747 series of common mode chokes. The series offers various inductance values tailored for different power line filtering requirements. The PA3747.505NL specifically targets applications needing moderate inductance with higher current tolerance compared to lower-current variants in the same family.

Common Mode Chokes Replacement Considerations

Direct substitutes must match the 5 mH inductance, 1.85 A current rating, and through-hole package dimensions. Verify impedance characteristics and DC resistance limits to ensure equivalent noise suppression performance without exceeding thermal limits.
