Procurement Notes
Verify component availability as distribution status may vary by region. Confirm RoHS compliance details through official documentation before integration. Check for end-of-life notifications or product change notices to ensure long-term supply chain stability. Validate that the specific suffix matches required packaging options such as cut tape or reel formats.
Selection Notes
Select this model when a 270 µH inductance value is required with moderate current handling capabilities. The shielded design is suitable for space-constrained boards needing reduced magnetic coupling. Ensure the 920 mA rating aligns with peak load requirements. Compare physical dimensions against board layout constraints prior to finalization.
Part Context
This component belongs to the B953AS series of fixed power inductors manufactured by Murata Electronics. The series offers various inductance values within a consistent form factor. These parts are designed for surface-mount technology applications requiring reliable energy storage and noise suppression in compact electronic assemblies.
Replacement Considerations
Consult official distributor databases for verified substitute part numbers. Cross-reference electrical parameters including inductance, current ratings, and physical dimensions to ensure functional compatibility. Verify package compatibility before substituting.
