Fixed Inductors Procurement Notes

Verify the specific suffix 'F' indicates RoHS compliance status as per manufacturer documentation. Confirm that the 140 mΩ DC resistance value aligns with thermal management requirements for the target application. Ensure the 1.8 A current rating accommodates peak load conditions without saturation. Cross-reference the physical dimensions against the PCB footprint to guarantee mechanical fitment during assembly.

Fixed Inductors Selection Notes

Select this component when a shielded SMD inductor is required for power stages. The 47 µH value suits moderate frequency switching applications. Consider the 1.8 A rating against continuous and peak load demands. The shielded design is advantageous where EMI sensitivity exists. Evaluate the 140 mΩ resistance impact on overall system efficiency and heat dissipation constraints.
