Common Mode Chokes Procurement Notes

Verify the specific suffix 'U' against the manufacturer's latest documentation to confirm packaging configuration, as suffixes may denote tape-and-reel specifications or regional compliance variations. Confirm RoHS status directly from the official datasheet. Note that availability may vary by region; check authorized distributors for current stock levels and lead times before finalizing procurement plans.

Common Mode Chokes Selection Notes

Select this component when space constraints require a 0603 footprint for common mode filtering. Ensure the required impedance matches the 90 Ohm specification at 100 MHz. Verify that the circuit's DC current does not exceed 130 mA to prevent saturation. Consider the 2 Ohm DC resistance impact on power consumption. This part is suitable for interfaces requiring moderate noise attenuation without significant signal degradation.

Common Mode Chokes Part Context

This component belongs to the Panasonic EXC18CE series of common mode filters. These devices are engineered for Mbps and Gbps transmission lines. The series offers various impedance values while maintaining a consistent small and thin form factor. The EXC18CE series utilizes ferrite core materials to achieve high Q values in the GHz zone, ensuring effective high-frequency noise suppression.

Common Mode Chokes Replacement Considerations

Check Panasonic's official substitution guide for direct replacements within the EXC18CE series. Other manufacturers may offer equivalent 0603 common mode chokes, but pin compatibility and impedance curves must be verified against the original datasheet specifications.
