Common Mode Chokes Procurement Notes

Verify the specific suffix and packaging configuration against official Delevan documentation before ordering. Confirm that the required inductance value and current rating align with the circuit design specifications. Ensure compatibility with the target PCB footprint and lead spacing requirements. Check for any RoHS compliance status updates directly from the manufacturer.

Common Mode Chokes Selection Notes

Select this component when a 1500 µH common mode choke is required for through-hole assembly. Consider the 700 mA current limit and 306 mΩ resistance for power loss calculations. Evaluate the unshielded nature against nearby sensitive components. Compare thermal performance within the specified operating temperature range.

Common Mode Chokes Part Context

This part belongs to the CM9900R series of PC mount common mode chokes. The series offers various inductance values tailored for different filtering needs. Delevan produces these components using ferrite cores and radial leads. The CM9900R-155 specifically targets applications requiring moderate inductance with high current handling capabilities.

Common Mode Chokes Replacement Considerations

Consult official Delevan cross-reference lists for verified substitutes. Ensure replacement parts match the 1500 µH inductance, 700 mA current rating, and 5.1 mm lead spacing. Verify identical package dimensions and mounting style.
