Common Mode Chokes Procurement Notes

Verify the complete part number including the -Z suffix to ensure correct material specification and termination style. Confirm that the surface mount footprint matches the target PCB layout dimensions. Check datasheet specifications for impedance tolerance and thermal operating limits before integration into the final assembly.

Common Mode Chokes Selection Notes

Select this component when dual-channel common mode rejection is required for high-frequency signals. The 4S2 material offers specific permeability characteristics suitable for applications above 10 MHz. Evaluate the low DC resistance requirement against the circuit's power consumption constraints to ensure minimal voltage drop across the filter.

Common Mode Chokes Part Context

This component belongs to the CMS2 series of common mode chokes from Ferroxcube. The series provides various impedance values and channel configurations to suit different filtering needs. The 4S2 material designation indicates a specific ferrite formulation chosen for its magnetic properties at higher frequencies compared to standard materials.

Common Mode Chokes Replacement Considerations

Substitute parts must match the 38 Ohm impedance at 25 MHz and the 600 microohm DCR. Verify that alternative components support the same surface mount package dimensions and pin configuration to maintain mechanical compatibility without redesigning the PCB.
