Procurement Notes
Verify component status as the part is listed as obsolete. Confirm availability through authorized distributors or surplus suppliers. Ensure compatibility with existing PCB layouts due to the nonstandard package dimensions. Validate RoHS compliance status prior to integration into new designs.
Selection Notes
Select this component for RF applications requiring 27 µH inductance with low current handling capabilities. Consider the unshielded nature when designing near sensitive components. Verify that the 55 mA current rating meets circuit requirements. Assess thermal management needs given the 8 Ohm DC resistance.
Part Context
This component belongs to the Delevan RF inductor portfolio, specifically designed for surface-mount technology. It serves as a passive element for radio frequency signal conditioning. The product line emphasizes established reliability for specialized electronic assemblies.
Replacement Considerations
As the part is obsolete, identify equivalent unshielded SMD RF inductors with 27 µH inductance and similar current ratings. Verify package footprint compatibility before substitution.
