Common Mode Chokes Procurement Notes

Verify the specific part number suffix against official API Delevan documentation to confirm exact electrical characteristics and compliance status. Ensure that the required inductance value and current rating align with the target circuit design before procurement. Cross-reference manufacturer datasheets for any recent product change notifications or environmental compliance updates.

Common Mode Chokes Selection Notes

Select this component when a low-inductance common mode choke is required for high-current data lines. Compare the 7.19 Ohm DC resistance against allowable voltage drop constraints. Consider the physical footprint and lead spacing compatibility with existing PCB layouts. Evaluate thermal performance at the maximum operating temperature of +125°C.

Common Mode Chokes Part Context

This component belongs to the CM9900 series of common mode chokes manufactured by API Delevan. The series offers various inductance values tailored for different filtering requirements. The CM9900-473 specifically targets applications needing moderate inductance with higher current handling capabilities compared to higher inductance variants in the same family.

Common Mode Chokes Replacement Considerations

Consult official manufacturer substitution lists for verified equivalents. Generic replacements may differ in core material, saturation characteristics, or physical dimensions. Verify that any substitute maintains the same lead spacing and mounting style to ensure mechanical compatibility.
