Procurement Notes
This part is scheduled for obsolescence and will be discontinued by the manufacturer. Public notices indicate an End-of-Life (EOL) or Obsolete status with a final shipment date around March 2026. Verify current availability through authorized distributors as stock may be limited. Confirm RoHS3 compliance and MSL Level 1 status before procurement planning.
Selection Notes
Select this component when a 27 µH inductance with high current handling capability is required in a compact surface mount form factor. Ensure the application current does not exceed the 2.3 A rated current or 2.4 A saturation current limits. Consider the nonstandard footprint dimensions during PCB layout. Evaluate alternative parts if long-term supply continuity is critical due to the obsolescence notice.
Part Context
The B966BS series consists of shielded power inductors manufactured by Murata Electronics. These components are characterized by low DC resistance and high saturation currents suitable for demanding power applications. The specific model #B966BS-270M=P3 represents the 27 µH variant within this family, utilizing a standard drum core geometry.
Replacement Considerations
Public sources confirm that the B966BS series is being phased out. No specific substitute part numbers are explicitly documented in the provided reference data. Designers should consult Murata's official documentation for recommended replacement families or equivalent specifications from other manufacturers.
