Fixed Inductors Procurement Notes

Verify the specific suffix 'L2' against official datasheets to confirm packaging and tape specifications. Confirm RoHS3 compliance status directly with the manufacturer or authorized distributors. Ensure the ordering part number matches the exact electrical parameters required for the design. Check for any recent updates to the component's lifecycle status or recommended replacement parts.

Fixed Inductors Selection Notes

Select this component when a low-inductance value of 250 nH is required for high-speed switching applications. Consider the 39 A rated current and 28 A saturation current limits to ensure adequate headroom for peak load conditions. The unshielded design may require layout considerations to manage electromagnetic interference. Verify thermal performance within the specified -40°C to 125°C operating range.
