Overview
The #A914BYW-4R7M=P3 is a shielded surface-mount power inductor from Murata Electronics, designed for power line choke applications. It features a ferrite core and wirewound construction within a 2020 (5252 metric) package measuring 5.2 mm x 5.2 mm x 2 mm. The component provides an inductance of 4.7 µH with a tolerance of ±20%. It supports a maximum DC current of 1.22 A and has a maximum DC resistance of 87 mOhms. The saturation current is rated at 1.22 A. Operating temperatures range from -40°C to +85°C.
Feature Summary
- Shielded design minimizes electromagnetic interference in compact layouts
- Ferrite core construction ensures stable performance under load
- Surface-mount format facilitates automated assembly processes
Applications
- Power line chokes
- DC-DC converter output filtering
- General power supply circuits
Procurement Notes
Verify the specific suffix =P3 against official manufacturer documentation to confirm compliance requirements and material specifications. Confirm availability status as distribution channels may vary. Ensure the 2020 footprint matches the target PCB design constraints before finalizing procurement orders.
Selection Notes
Select this component when a compact 5.2mm x 5.2mm shielded inductor is required for power filtering. The 4.7 µH value and 1.22 A current rating suit moderate power applications. Verify that the 87 mOhm DCR meets efficiency targets and that the saturation current aligns with peak load conditions.
Part Context
This part belongs to the A914BYW series of power inductors. It shares the same physical dimensions and shielding characteristics as other variants in the family, such as the #A914BYW-150M=P3, but differs in inductance value and current handling capabilities. The series is characterized by its small form factor suitable for dense electronic assemblies.
Replacement Considerations
Direct substitutes within the same series include #A914BYW-6R8M=P3 and #A914BYW-560M=P3, though these have different inductance values. Cross-series replacement requires matching the 2020 footprint and verifying electrical parameters against the original design requirements.
