Procurement Notes
This component is scheduled for obsolescence and will be discontinued by the manufacturer. Availability is limited, and sourcing may require checking existing stock or alternative distributors. Verify end-of-life status and lead times carefully before finalizing procurement plans to ensure production continuity.
Selection Notes
Select this inductor when a 10 µH value with high current handling capability is required. Ensure the application fits the nonstandard footprint dimensions. Consider the 4.3 A rating for thermal management. Verify compatibility with surface mount reflow processes and check for suitable replacement parts due to discontinuation status.
Part Context
This part belongs to Murata's fixed inductor series, specifically designed for power electronics. It falls under the category of shielded power inductors, distinguishing it from unshielded variants. The model number indicates specific electrical parameters and packaging configuration within the manufacturer's catalog structure.
Replacement Considerations
Due to the obsolescence notice, verify equivalent components with matching 10 µH inductance, 4.3 A current rating, and compatible physical dimensions. Consult manufacturer substitution guides for cross-referenced parts that maintain circuit performance without redesign.
