Procurement Notes
Verify the specific suffix and manufacturer part number against official Murata documentation before procurement. Confirm that the component meets all required electrical specifications for the target application. Check current availability status as supply conditions may vary. Ensure compliance with RoHS directives if required by the end product standards.
Selection Notes
Select this component for applications requiring a 10 uH inductance with a 1.49 A current rating. Consider the 90 mOhms DCR for efficiency calculations in power paths. The 2020 package size is appropriate for standard surface mount processes. Evaluate thermal performance at the specified operating temperature limits.
Part Context
This part belongs to Murata's fixed inductor family, specifically optimized for power electronics. It serves as a passive energy storage element in switching regulators. The shielded design distinguishes it from unshielded alternatives by reducing magnetic field leakage. It is intended for use in automotive and industrial embedded systems.
Replacement Considerations
Consult official Murata substitution guides for verified alternative part numbers. Do not assume cross-compatibility based on similar inductance values alone. Verify pinout and mechanical dimensions match the existing PCB layout before replacement.
