Fixed Inductors Procurement Notes

Verify the specific suffix (e.g., H) against the manufacturer's official datasheet to confirm exact electrical tolerances and packaging configurations. Ensure that the required operating temperature range aligns with the component's specified limits. Confirm RoHS compliance status as indicated in the product documentation prior to final procurement decisions.

Fixed Inductors Selection Notes

Select this component when a precise 43 µH inductance is required for RF applications with strict tolerance needs. Consider the unshielded nature for layout planning to prevent unintended coupling. Evaluate the 1.1 A current rating against peak circuit loads to ensure reliable operation under all expected conditions.
