Procurement Notes
Verify RoHS compliance status through official manufacturer documentation prior to procurement. Confirm lead-free soldering compatibility if required by assembly standards. Check for obsolescence or lifecycle changes as availability may vary. Ensure the specific suffix matches the required tolerance and current ratings for the target application.
Selection Notes
Select this component when a 27 µH inductance value is required within a standard 2725 metric footprint. Consider the 120 mA current limit and 6.9 Ohm DC resistance during thermal and efficiency calculations. Verify that the unshielded nature does not interfere with nearby sensitive components due to potential magnetic field emission.
Part Context
This part belongs to the Delevan 103/R series of fixed inductors. These components are characterized by their unshielded wirewound architecture and ferrite cores. The series offers various inductance values tailored for RF and general electronic applications, maintaining consistent physical dimensions across the range.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source data. Engineers should consult official manufacturer cross-reference lists or datasheets for verified equivalent components.
