Applications
- High-speed data line filtering
- Power supply noise suppression
- EMI/RFI mitigation in portable devices
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels due to obsolete status. Confirm RoHS3 compliance and MSL level 1 handling requirements during storage and assembly. Cross-reference datasheet revisions to ensure parameter consistency with original specifications before integration into production workflows.
Selection Notes
Select this component when low impedance values are required for minimal signal attenuation in high-current paths. Ensure the 600mA current rating exceeds the application's peak load to prevent saturation. Verify that the 0402 footprint matches the PCB layout constraints and that the thermal characteristics align with the system's operational environment.
Part Context
This part belongs to the BK series of multilayer chip bead inductors manufactured by Taiyo Yuden. These components are engineered for effective electromagnetic interference suppression in compact electronic designs. The BK series utilizes specialized ferrite materials to provide stable performance across a broad frequency spectrum while maintaining small physical dimensions.
Replacement Considerations
Publicly confirmed substitutes include ACML-050-T by Abracon LLC and BLM15BB050SN1D by Murata Electronics. Verify electrical parameters such as impedance, current rating, and DC resistance against these alternatives to ensure functional equivalence in the specific circuit application.
