Procurement Notes

Verify the specific suffix designation when ordering, as variations such as CM6350R-225 may exist within the series. Confirm RoHS compliance status directly with the manufacturer or authorized distributor documentation prior to finalizing procurement decisions. Ensure the selected variant matches the required pinout and mechanical footprint specifications for the target application board layout.

Selection Notes

Select this component based on its 2.2 mH inductance rating which targets specific frequency attenuation requirements. Evaluate the 600 mA current handling capability against the circuit's operational load to prevent saturation. Consider the 300 mΩ DC resistance impact on signal loss and power efficiency. The compact 4-pin SMD form factor is critical for space-constrained designs requiring reliable EMI mitigation without increasing board profile.

Part Context

This component belongs to the CM6350 series of common mode chokes manufactured by API Delevan. The series offers various inductance values tailored for different filtering needs. The CM6350-225 specifically addresses applications requiring moderate inductance for noise reduction in digital communication interfaces. It represents a standard solution for maintaining signal integrity in electronic systems susceptible to electromagnetic interference.

Replacement Considerations

The CM6350R-225 is a documented variant within the same series. Verify if the 'R' suffix indicates any functional or packaging differences before substitution. Cross-reference electrical parameters such as inductance and current ratings to ensure compatibility.
