Procurement Notes
Verify availability status carefully as this part may be subject to limited supply or factory special orders. Confirm RoHS compliance details and check for any Product Change Notices (PCN) regarding assembly or sourcing changes before finalizing procurement plans. Ensure the ordering suffix matches the required packaging configuration.
Selection Notes
Select this component when a compact shielded inductor with specific 22 µH inductance is required. Consider the 530 mA continuous current rating and 500 mA saturation limit against circuit load requirements. The 672 mΩ DCR impacts efficiency; ensure thermal management aligns with the -40°C to +85°C operating range for the target application environment.
Part Context
This part belongs to the A914BYW series of power inductors manufactured by Murata Electronics. The series includes various inductance values such as 2.2 µH and 33 µH variants. The =P3 suffix indicates specific packaging or handling characteristics defined by the manufacturer. These components are generally used in portable electronics and industrial equipment requiring reliable SMD power filtering.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-reference with other Murata SMD power inductors only if electrical parameters match exactly. Verify compatibility with existing PCB footprints and reflow soldering profiles before substitution.
