Procurement Notes
Verify availability status carefully as this part may be subject to limited supply or discontinuation. Confirm RoHS compliance details through official documentation before integration. Ensure the ordering suffix matches specific packaging requirements such as cut tape or reel formats. Cross-reference the manufacturer number with authorized distributors to avoid counterfeit components during sourcing.
Selection Notes
Select this component when a 15 µH inductance value is required with a 1.8 A continuous current rating. The shielded structure is appropriate for environments sensitive to magnetic coupling. Verify that the 63 mΩ DC resistance meets efficiency targets. Ensure the operating temperature range of -40°C to +85°C aligns with the system's thermal constraints.
Part Context
This component belongs to the A921CY series of power inductors manufactured by Murata Electronics. The series focuses on compact, shielded SMD solutions for general electronics. The specific model utilizes a wirewound ferrite core architecture to balance inductance stability with current handling capabilities in small form factors.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source data. Consult official Murata resources for potential alternatives if this component is discontinued or unavailable.
