Procurement Notes
Verify component availability status as the part may be discontinued or subject to limited supply. Confirm RoHS compliance details through official manufacturer documentation prior to procurement. Ensure that ordering suffixes do not alter functional specifications unless explicitly stated in the datasheet. Cross-reference with authorized distributors for accurate lead times and packaging quantities.
Selection Notes
Select this component for applications requiring a 1.2 µH inductance with low DC resistance in a compact surface-mount package. Consider the 310 mA current rating and 1 Ohm resistance for power handling requirements. The unshielded design requires careful layout consideration to minimize electromagnetic interference coupling in dense circuit boards.
Part Context
This part belongs to the 105/R series of fixed inductors manufactured by API Delevan. It is categorized under RF Inductors - SMD within the broader inductors, chokes, and coils subcategory. The component is designed for high-frequency applications where standard surface-mount technology integration is required.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative components based on electrical parameters and physical footprint if direct replacement is necessary.
