Procurement Notes
Verify RoHS compliance status as sources indicate lead-containing variants may exist. Confirm package dimensions and terminal type against specific datasheet revisions. Check availability status as this component may be discontinued or have limited supply. Ensure supplier documentation matches the exact part number suffix for accurate electrical parameters.
Selection Notes
Select this component when a 220 nH inductance value is required with moderate current handling capabilities. Consider the unshielded nature for layout sensitivity regarding magnetic interference. Verify that the 675 mA current rating meets the application's peak load requirements. Compare thermal performance at the upper operating limit of 125°C.
Part Context
This part belongs to the Delevan 105 series of fixed inductors. The series includes various inductance values and tolerances, such as the 105-221H and 105-271K. These components are typically used in RF and power applications requiring reliable surface-mount solutions.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided data. Cross-reference with other 105 series variants like 105-221H if parameter adjustments are acceptable.
