Common Mode Chokes Procurement Notes

Verify the specific impedance tolerance and DC resistance values against the official Eaton datasheet prior to procurement. Confirm that the 4-pin SMD footprint matches the target PCB layout. Ensure the selected variant meets the required thermal management standards for the intended operating environment.

Common Mode Chokes Selection Notes

Select this component when designing circuits requiring significant attenuation of common mode noise at 100 MHz. The 1.0 A current rating suits moderate power applications. Verify that the 63 mOhm DCR does not cause excessive voltage drop in the signal path compared to lower impedance alternatives.
