Procurement Notes
Verify component availability status as listings indicate obsolete or limited stock conditions. Confirm RoHS compliance details through official manufacturer documentation prior to procurement. Ensure the specific lead configuration matches the target PCB footprint requirements for this nonstandard package type.
Selection Notes
Select this component when a 3.9 µH inductance with low current handling capability is required. The high DC resistance of 2.8 Ohms limits suitability for high-power applications. Consider the unshielded nature for potential EMI implications in dense layouts compared to shielded alternatives.
Part Context
This part belongs to the Delevan 105R series of fixed surface-mount inductors. The series offers various inductance values tailored for RF and general electronics. The 105R-392G specifically addresses needs for moderate inductance with minimal current draw in space-constrained designs.
Replacement Considerations
Cross-reference with other 3.9 µH SMD inductors ensuring compatible current ratings and physical dimensions. Verify that substitute components match the two-lead termination style if existing board space is constrained.
