Procurement Notes
Verify RoHS compliance status carefully as historical data indicates potential lead content variations across manufacturing batches. Confirm the specific suffix designation against the latest manufacturer datasheet to ensure correct material composition and environmental certification before finalizing procurement orders.
Selection Notes
Select this component when precise 10 µH inductance is required in space-constrained RF designs. The unshielded nature necessitates careful PCB layout to minimize electromagnetic interference coupling. Ensure the 165 mA current limit aligns with the application's peak load requirements to prevent saturation.
Part Context
This part belongs to the Delevan 103 series, characterized by small form-factor surface-mount inductors. The 'R' suffix typically denotes specific packaging or variant configurations within the product line. These components are engineered for high-frequency stability and are commonly integrated into telecommunications and consumer electronic hardware.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Cross-referencing requires manual verification of electrical parameters and physical dimensions against alternative manufacturers' catalogs.
