Procurement Notes
Verify the specific package dimensions and lead configuration against the official datasheet before integration, as the component is described as having a nonstandard form factor. Confirm availability status through authorized channels, as manufacturing status may vary. Ensure that the 135 mA current rating meets the operational requirements of the target circuit to prevent saturation or thermal issues during implementation.
Selection Notes
Select this component when a precise 8.2 µH inductance is required for RF or signal processing tasks. The unshielded nature makes it suitable for layouts where magnetic interference is not a primary constraint. Consider the 5 Ohm DC resistance impact on power loss and the 135 mA limit for current handling capabilities within the specific application environment.
Part Context
This part belongs to the API Delevan family of micro chip inductors. These components are engineered for high-frequency performance and compact integration into electronic systems. The 105 series represents a specific line of fixed inductors designed to provide stable inductive values for tuning and filtering purposes in various electronic assemblies.
Replacement Considerations
Check DigiKey listings for substitute options if this specific part is discontinued. Verify that any replacement maintains the 8.2 µH inductance, similar current ratings, and compatible physical footprint to ensure seamless integration without redesigning the printed circuit board layout.
