Fixed Inductors Procurement Notes

This component is officially designated as End-of-Life (EOL) by Samsung Electro-Mechanics. Verification of final stock availability through authorized distributors is required before integration into new designs. Engineers must confirm that existing inventory meets project timelines or initiate immediate transition plans to approved substitute components to avoid supply chain disruption.

Fixed Inductors Selection Notes

Designers should prioritize this component only if the specific 3.3 nH inductance and 0201 form factor are strictly necessary for impedance matching. Due to its EOL status, alternative sourcing strategies must be evaluated. Considerations include verifying that substitute components offer equivalent Q values and self-resonant frequencies to maintain RF performance without redesigning the PCB layout.
