Procurement Notes

This component is scheduled for obsolescence and will be discontinued by the manufacturer. Verify end-of-life status and availability through official channels before finalizing designs. Ensure compliance with RoHS directives as indicated in product documentation. Confirm lead times and stock levels with authorized distributors, noting that supply may be limited due to the discontinuation notice.

Selection Notes

Select this inductor for applications requiring compact shielding and high current handling. The 1.0 µH value suits low-inductance filtering needs. Verify thermal performance at operating currents near the 4.52 A rating. Consider the nonstandard package dimensions for PCB layout constraints. Evaluate saturation characteristics against peak load requirements to prevent performance degradation.
