Procurement Notes
Verify component availability as this model may be discontinued or obsolete. Confirm RoHS compliance status through official documentation before procurement. Ensure the specific tolerance variant matches circuit requirements, as other variants exist within the same series. Cross-reference datasheets to confirm lead-free status and material composition.
Selection Notes
Select this component for low-current RF applications requiring 1.8 µH inductance. Consider the 1.5 Ohm DC resistance impact on power loss. Evaluate the unshielded nature regarding electromagnetic interference susceptibility. Compare against shielded alternatives if magnetic coupling is a concern. Verify operating temperature ranges against environmental conditions.
Part Context
This component is part of the API Delevan Micro i Chip Inductors family. It shares design principles with other unshielded SMD inductors from the manufacturer. The product line focuses on compact form factors for high-frequency electronics. Similar parts include variations in inductance values and current ratings within the 105 series.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided data. Check for direct pin-compatible alternatives from API Delevan or other manufacturers offering similar RF specifications. Verify electrical parameters match exactly when sourcing replacements.
