Fixed Inductors Procurement Notes

Verify the specific ordering suffix matches the required inductance value and tolerance. Confirm that the package type aligns with the intended manufacturing process. Ensure the thermal rating meets the operational environment requirements. Cross-reference the datasheet parameters against the bill of materials specifications before finalizing procurement decisions.

Fixed Inductors Selection Notes

Select this component when an unshielded inductor is acceptable for the application layout. Consider the 700 mA heating current limit for continuous operation scenarios. Evaluate the 950 mA saturation threshold against peak load conditions. Verify that the 351 mΩ resistance fits within the system's efficiency constraints.
