Common Mode Chokes Procurement Notes

Verify the current lifecycle status before procurement as this specific part number may be discontinued or subject to supply restrictions. Confirm that the 90-ohm impedance specification aligns with your transmission line requirements. Ensure the 2 mm x 1.25 mm footprint matches your PCB layout constraints. Check for RoHS compliance documentation if required by your manufacturing standards.

Common Mode Chokes Selection Notes

Select this component when designing circuits requiring simultaneous ESD suppression and common mode noise filtering for differential pairs. The 90-ohm impedance makes it suitable for maintaining characteristic impedance in high-speed digital interfaces. Consider the 0.4 pF capacitance value to ensure minimal signal degradation at high frequencies. Verify that the 5 V operating voltage meets the system's electrical requirements.

Common Mode Chokes Part Context

This device belongs to Murata's LXESxxD series of ESD protection components. These parts are engineered specifically for protecting sensitive electronic interfaces from electrostatic discharge events while preserving signal quality. The series typically includes variants with different channel counts and impedance values to suit various interface standards.

Common Mode Chokes Replacement Considerations

Consult official Murata documentation for verified substitute part numbers. Cross-reference impedance, channel count, and package dimensions when evaluating alternatives. Ensure any replacement maintains the 90-ohm impedance requirement for proper signal matching.
