Procurement Notes

Verify the specific datasheet version for the 7448640410, as manufacturer documentation may list variations such as 2.7 mH or 1.2 A ratings for similar part numbers in the same series. Confirm that the 3.6 mH / 1.55 A specifications match your design requirements before ordering. Ensure compatibility with through-hole PCB layouts.

Selection Notes

Select this component when high inductance is required for low-frequency noise suppression in single-phase power lines. The 0.22 ohm DC resistance offers a balance between filtering performance and power loss. Consider the physical dimensions and lead spacing for mechanical integration into the target enclosure.

Part Context

This component belongs to the WE-FC series of common mode chokes from Würth Elektronik. These inductors are engineered to suppress electromagnetic interference (EMI) on power lines. The series typically includes various inductance values and current ratings to suit different power levels and noise profiles in electronic equipment.

Replacement Considerations

Check for direct substitutes within the WE-FC series with matching inductance and current ratings. Verify pinout compatibility and physical footprint if replacing existing components on a PCB.
