Common Mode Chokes Procurement Notes

Verify the specific ordering suffix and manufacturer part number against official Eaton documentation to ensure compatibility. Confirm that the surface-mount footprint matches the design layout. Check for any recent product change notices or obsolescence announcements regarding the CMS series before finalizing procurement plans.

Common Mode Chokes Selection Notes

Select this component when designing circuits requiring compact common mode filtering for low-to-medium current applications. Ensure the required inductance value at the operating frequency meets EMI standards. Verify that the 2.6 A current rating accommodates peak loads without saturation. Consider the thermal dissipation capabilities given the 19 mΩ DCR in high-current environments.

Common Mode Chokes Part Context

This component belongs to the Eaton CMS series of surface-mount common mode chokes. These components are engineered for space-constrained designs where traditional through-hole inductors are unsuitable. The series offers various inductance values to suit different filtering requirements while maintaining a consistent form factor for board layout flexibility.
