Common Mode Chokes Procurement Notes

Verify the specific manufacturer part number against official Delevan documentation to ensure accuracy. Confirm that the required inductance value and current rating align with the circuit design specifications. Check for RoHS compliance status if restricted substances are a constraint. Ensure the physical dimensions and lead spacing fit the target PCB layout constraints before finalizing procurement.

Common Mode Chokes Selection Notes

Select this component when a 3.3 mH common mode choke is required for through-hole assembly. The 550 mA current rating and 531 mOhm resistance define the electrical limits. Verify that the unshielded nature does not interfere with nearby sensitive components. Ensure the operating temperature range meets the environmental requirements of the application.

Common Mode Chokes Part Context

This component belongs to the Delevan CM9900R series of common mode chokes. The series offers various inductance values while maintaining consistent physical dimensions and mounting styles. These parts are designed for general-purpose electromagnetic interference suppression in electronic circuits requiring through-hole integration.

Common Mode Chokes Replacement Considerations

Other CM9900R series variants such as CM9900R-225 or CM9900R-185 share identical mechanical footprints and mounting characteristics. Substitution requires verifying that the alternative inductance and current ratings meet the specific circuit requirements.
