Common Mode Chokes Procurement Notes

Verify the specific suffix and revision level against the manufacturer's latest datasheet to ensure compatibility with design requirements. Confirm RoHS compliance status and moisture sensitivity level prior to procurement. Check for any product change notices or obsolescence alerts associated with this part number before finalizing supply chain decisions.

Common Mode Chokes Selection Notes

Select this component when surface-mount technology is required for power line applications involving currents up to 4.1 A. Ensure the PCB layout accommodates the specified 9.40mm x 7.20mm dimensions and 2.60mm height. Verify that the 12.6 µH inductance value meets the circuit's noise suppression requirements at the target frequency.

Common Mode Chokes Part Context

This component belongs to the Eaton CMS series of common mode chokes, which are engineered for surface-mount applications. The series offers various inductance and current ratings to suit different power line filtering needs. The CMS1-3-R specifically addresses scenarios requiring moderate inductance with higher current handling capabilities in a compact form factor.

Common Mode Chokes Replacement Considerations

Direct substitutes may include other surface-mount common mode chokes from Eaton or compatible manufacturers with similar electrical characteristics (12.6 µH, 4.1A) and mechanical dimensions. Verify pinout compatibility and thermal performance before substitution.
