Fixed Inductors Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to ensure correct tolerance and packaging specifications. Confirm that the selected variant matches the required inductance value and current rating for the target application circuit. Check for any recent product change notices or lifecycle status updates directly from the supplier before finalizing procurement plans.

Fixed Inductors Selection Notes

Select this component when a low-inductance, high-frequency solution is required for space-constrained designs. Ensure the operating current remains below the 400 mA saturation limit to maintain stable inductance values. Consider the unshielded nature of the device regarding potential electromagnetic interference coupling with adjacent sensitive traces on the PCB layout.
