Common Mode Chokes Procurement Notes

Verify the specific ordering suffix and package variant against the official Panasonic datasheet before procurement. Confirm that the component status aligns with project timelines, as availability may be affected by manufacturer lifecycle announcements. Ensure compatibility with automated placement equipment regarding the 0302 package dimensions and terminal configuration.

Common Mode Chokes Selection Notes

Select this component when designing high-speed digital interfaces requiring minimal insertion loss and significant common mode attenuation. Evaluate the 35 Ohm impedance value against the target frequency spectrum to ensure adequate noise suppression without distorting signal integrity. Consider the 0.1 A current rating to verify suitability for the specific power requirements of the protected circuit lines.

Common Mode Chokes Part Context

This part belongs to the EXC series of common mode noise filters from Panasonic Industry. These components are engineered for suppressing electromagnetic interference in high-speed data transmission lines. The series offers various impedance values and package sizes to accommodate different bandwidth requirements and board space limitations in modern consumer electronics.

Common Mode Chokes Replacement Considerations

Check for direct substitutes within the EXC series or equivalent offerings from other manufacturers. Verify that any replacement matches the 35 Ohm impedance, 0302 package, and 0.1 A current rating. Confirm pinout compatibility and thermal characteristics to ensure seamless integration into existing PCB layouts.
