Procurement Notes

Verify the component status as this part may be subject to obsolescence or discontinuation notices from the manufacturer. Confirm availability through authorized distributors and check for valid replacement alternatives if the specific model is no longer recommended for new designs.

Selection Notes

Select this component when a low-profile, multi-channel LC filter is required for high-frequency noise reduction. Ensure the application current does not exceed 100 mA and the operating environment remains within the specified temperature limits. Verify compatibility with standard SMT assembly processes.

Part Context

This component belongs to the Murata NFA18SL series of combined EMI filters. The series is characterized by its small size and deep insertion loss capabilities. It is designed to replace discrete components with a single integrated solution for improved performance and board space efficiency.

Replacement Considerations

Check for official substitute part numbers from Murata Electronics if this item is discontinued. Verify that any alternative maintains the same 0603 package dimensions, channel count, and electrical specifications to ensure mechanical and functional compatibility.
