Procurement Notes
Verify component status carefully as this part is scheduled for obsolescence and will be discontinued by the manufacturer. Confirm availability through authorized distributors before finalizing procurement plans. Ensure that the specific suffix matches the required specifications. Check for alternative components if long-term supply stability is a priority for the production line.
Selection Notes
Select this component when a shielded wirewound inductor with 4.7 µH inductance is required. Ensure the circuit design accommodates the 5.4 A current rating and 18 mΩ DCR. Verify that the nonstandard package dimensions fit the PCB layout constraints. Consider the obsolescence status when planning for future product generations or extended lifecycle requirements.
Part Context
This inductor belongs to the B966AS series from Murata Electronics, designed for power applications. It shares characteristics with other fixed inductors in the lineup but is distinguished by its specific 4.7 µH value and 5.4 A rating. The series typically offers shielded designs to minimize electromagnetic interference in compact power systems.
Replacement Considerations
Due to the scheduled obsolescence, verify equivalent parts with similar electrical parameters such as 4.7 µH inductance and comparable current ratings. Consult Murata's official documentation for recommended replacements within the same family or newer series that maintain functional compatibility.
