Procurement Notes
Verify the specific suffix and manufacturer designation carefully when sourcing this component. Confirm that the requested part matches the exact Murata Electronics model number to ensure compatibility with existing circuit designs. Check current availability status as distribution channels may vary. Ensure that the procurement source provides authentic components with proper documentation to maintain system reliability and performance standards.
Selection Notes
Select this inductor when a compact 2020 footprint is required for power filtering applications. The 47 µH value and 750 mA current rating suit moderate power handling needs. Consider the low DC resistance for efficiency optimization. Verify thermal requirements against the operating temperature range. Ensure the shielded type meets electromagnetic compatibility constraints for the specific electronic assembly.
Part Context
This component belongs to the A915BY series of fixed power inductors manufactured by Murata Electronics. The series offers various inductance values within the same physical package dimensions. These inductors are engineered for automotive and industrial applications requiring reliable performance under varying environmental conditions. The shielded design distinguishes them from unshielded alternatives in the broader inductor portfolio.
Replacement Considerations
Consult official Murata documentation for direct cross-references. Verify pinout compatibility and electrical parameters before substitution. Ensure the alternative component meets the same voltage and current ratings. Check mechanical dimensions to confirm fit within the designated PCB footprint.
