Common Mode Chokes Procurement Notes

Verify the current lifecycle status before procurement, as multiple sources indicate this part is scheduled for obsolescence or discontinued. Confirm availability through authorized distributors only. Ensure that any substitute components meet the original electrical specifications, particularly impedance and current ratings, to maintain circuit integrity. Validate RoHS compliance if required by your manufacturing standards.

Common Mode Chokes Selection Notes

Select this component when space constraints necessitate a 0302 footprint. Ensure the application requires 43 Ohm impedance at 100 MHz for effective noise filtering. Verify that the circuit's DC current does not exceed 100 mA to prevent saturation. Consider the 2.7 Ohm DCR impact on signal loss. Evaluate alternative packages if higher current handling is needed.

Common Mode Chokes Part Context

This component belongs to Panasonic's EXC series of common mode chokes, specifically designed for high-frequency noise suppression in small form factors. The EXC-14CG430U variant targets applications requiring precise impedance characteristics in minimal board space. It serves as a specialized EMC/EMD solution within Panasonic's broader passive component portfolio.

Common Mode Chokes Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the specific 0302 package and 43 Ohm impedance profile, direct replacements must be sourced from manufacturer cross-reference lists. Verify compatibility with existing PCB footprints and thermal requirements.
