Common Mode Chokes Procurement Notes

Verify the specific suffix R indicates reel packaging when ordering. Confirm the manufacturer part number matches exactly to ensure correct impedance and current ratings. Check RoHS compliance status if required by project specifications. Ensure PCB footprint dimensions align with the specified horizontal package size before finalizing procurement.

Common Mode Chokes Selection Notes

Select this component when designing circuits requiring 6A current capacity and 300 Ohm impedance at 100 MHz. Consider the 80V DC rating for appropriate voltage headroom. Evaluate the compact horizontal footprint against available board space constraints. Compare thermal performance characteristics against other series options if operating near maximum temperature limits.

Common Mode Chokes Part Context

This component belongs to the ECMS-R series of common mode chokes from Eaton Electronics. The series offers various impedance and current combinations tailored for different power electronics needs. The ECMS1V0905 variant specifically targets applications requiring robust noise filtering in a small surface-mount form factor suitable for automated assembly processes.

Common Mode Chokes Replacement Considerations

Direct substitutes must match the 300 Ohm @ 100 MHz impedance, 6A current rating, and 6mOhm DCR. Verify pin compatibility and physical dimensions for direct replacement. Consult Eaton documentation for alternative part numbers within the same family that offer similar electrical characteristics.
