Procurement Notes
Verify component status carefully as this part is marked Not Recommended for New Designs (NRND) and scheduled for obsolescence. Confirm final availability through authorized distributors before integrating into new production plans. Check for official Product Change Notices regarding manufacturing origin or material updates. Ensure replacement strategies are defined prior to end-of-life implementation.
Selection Notes
Select this component when a 33 µH shielded inductor with 1.6 A rating fits the spatial constraints of a 10.40 mm square footprint. Verify that the 125 mOhm DCR meets efficiency requirements. Consider the limited operational temperature range compared to automotive-grade alternatives if harsh environments are involved. Evaluate alternative parts from the same manufacturer family for long-term supply security.
Part Context
This inductor belongs to the B952AS series of fixed power inductors manufactured by Murata Electronics. The series utilizes wirewound technology on a drum core structure. These components are designed for general-purpose power filtering and energy storage applications in compact electronic devices requiring surface mount integration.
Replacement Considerations
Consult Murata official documentation for confirmed substitute part numbers within the DEM series or equivalent B952 variants. Verify pin compatibility and electrical parameters before substitution.
