Common Mode Chokes Procurement Notes

Verify the specific suffix against official Eaton documentation to confirm exact electrical tolerances and packaging variations. Ensure the procurement channel provides valid RoHS compliance certificates. Cross-reference the manufacturer part number with authorized distributor databases to prevent counterfeit components. Confirm lead times directly with the supplier as standard delivery periods may fluctuate based on production schedules.

Common Mode Chokes Selection Notes

Select this component when high inductance is required for low-current applications. The 0.58 A rating suits compact power stages. Verify that the 0.44 ohm DCR aligns with system voltage drop constraints. Ensure the SMD footprint matches the PCB layout guidelines provided in the datasheet. Consider the 160°C temperature rating for high-heat environments.

Common Mode Chokes Part Context

This component belongs to the Eaton CMS series of common mode chokes. The series offers various inductance values and current ratings in standardized surface-mount packages. The CMS2-13-R specifically targets applications requiring significant attenuation at lower current levels compared to higher-rated variants in the same family.

Common Mode Chokes Replacement Considerations

Consult Eaton's official cross-reference tools for verified substitutes. Ensure any replacement maintains identical inductance, current rating, and physical dimensions to fit existing footprints without redesign.
