Common Mode Chokes Procurement Notes

Verify the specific inductance value of 3900 uH and the 440 mA current rating against your schematic requirements before ordering. Confirm that the 5.1 mm lead spacing matches your PCB footprint. Ensure the operating temperature range of -55 C to +125 C meets your environmental conditions. Check RoHS compliance status if required by your manufacturing standards.

Common Mode Chokes Selection Notes

Select this component when a 3900 uH common mode choke is required for through-hole assembly. Consider the 669 mOhms DC resistance impact on voltage drop. Evaluate the 440 mA saturation current against peak load demands. Compare physical dimensions against available board space constraints.

Common Mode Chokes Part Context

This part belongs to the Delevan CM9900R series of common mode chokes. The series offers various inductance values while maintaining consistent physical dimensions and mounting styles. Other variants include different inductance ratings such as 180 uH or 10000 uH, allowing designers to choose based on specific filtering needs within the same package form factor.

Common Mode Chokes Replacement Considerations

Consult official Delevan documentation for direct substitutes. Verify equivalent inductance, current rating, and physical dimensions when considering alternative manufacturers.
