Common Mode Chokes Procurement Notes

Verify the specific manufacturer designation, as sources list both API Delevan and Delevan. Confirm RoHS compliance status and tin plating details against the latest official datasheet. Ensure the 0.13 A rated current and 9.69 Ω DCR match design requirements before procurement.

Common Mode Chokes Selection Notes

Select this component when high inductance (68 mH) is required for low-current applications up to 0.13 A. The through-hole package suits prototyping or robust mechanical connections. Compare DCR and saturation characteristics against circuit load demands to ensure adequate performance without excessive voltage drop.

Common Mode Chokes Part Context

Part of the CM9900R series of PC mount common mode chokes. This series offers various inductance values ranging from microhenries to millihenries, all sharing similar physical footprints and through-hole mounting styles for standardized board layouts.

Common Mode Chokes Replacement Considerations

Check equivalent models within the CM9900R series for different inductance values if specifications allow. Verify pin compatibility and thermal ratings for direct substitution.
