Procurement Notes
Verify the specific ordering suffix against manufacturer documentation to confirm tolerance and packaging specifications. Ensure compatibility with standard surface-mount assembly processes. Confirm RoHS status and environmental compliance requirements prior to integration into final products.
Selection Notes
Select this component when a precise 1 uH inductance with 1% tolerance is required for RF circuits. Consider the 425 mA current rating and 540 mOhm resistance for power handling needs. The unshielded design requires consideration for electromagnetic interference in dense layouts.
Part Context
This part belongs to the 103/R series of fixed inductors from Delevan. It is categorized under RF Inductors - SMD within the broader Inductors, Chokes & Coils subcategory. The series is characterized by small form factors and standardized terminal configurations for automated placement.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided source data. Cross-reference with other 1 uH 1% tolerance SMD RF inductors only if electrical parameters and mechanical dimensions match exactly.
