Common Mode Chokes Procurement Notes

This component is scheduled for obsolescence and will be discontinued by the manufacturer. Availability is limited, and distributors may not stock this item in all regions. Verify end-of-life status and lead times carefully before finalizing designs. Consider alternative components with longer lifecycles for new production runs to ensure supply chain stability.

Common Mode Chokes Selection Notes

Select this part for applications requiring combined EMI filtering and ESD protection on single differential pairs. Ensure the 5 V operating voltage matches the system requirements. The WDFN-8 package size must fit the PCB layout constraints. Verify that the 1.3 pF capacitance meets the bandwidth requirements of the specific high-speed interface being protected.

Common Mode Chokes Part Context
