Fixed Inductors Procurement Notes

Verify the specific ordering suffix and packaging configuration required for production integration. Confirm that the component status aligns with long-term availability requirements, as manufacturing changes may occur. Ensure the selected package type matches automated assembly equipment capabilities. Cross-reference the manufacturer's latest documentation for any recent product change notices or lifecycle updates before finalizing procurement plans.

Fixed Inductors Selection Notes

Select this component when a shielded inductor is required to reduce magnetic field leakage in dense PCB layouts. The 3.00mm square package offers a balance between current handling and size. Verify that the 400 mA rated current meets the circuit's continuous load requirements. Consider the 888 mΩ DCR impact on overall efficiency. Ensure the operating temperature range covers the system's environmental extremes.
