Fixed Inductors Procurement Notes

This component is officially listed as obsolete by the manufacturer. Direct replacement availability may be limited. Verify end-of-life status with authorized distributors before finalizing designs. No new production is expected. Check for valid substitute part numbers from the same manufacturer family that match electrical and mechanical specifications.

Fixed Inductors Selection Notes

Select this part only if legacy compatibility is required due to its obsolete status. Compare DCR and saturation current against circuit requirements. Ensure the 4.5A rated current meets thermal constraints. Verify footprint compatibility with existing PCB layout. Consider newer Laird MGV or MGA variants if available.

Fixed Inductors Part Context

Part of the Laird MGA series of shielded power inductors. Designed for space-constrained applications requiring high current handling. Similar to MGV series but with distinct dimensional characteristics. Used in consumer, industrial, and automotive electronics where EMI compliance is critical.
