Procurement Notes

Verify the specific datasheet version to confirm electrical parameters, as documentation sources indicate variations in tolerance and current ratings for this model number. Confirm RoHS compliance status and package quantity requirements directly with the manufacturer or authorized distributors before finalizing procurement orders.

Selection Notes

Select this component for applications requiring a 680 nH inductance with axial leads. Ensure the operating environment accommodates the unshielded magnetic field. Verify that the required DC current does not exceed the rated limit to prevent saturation or thermal issues.

Part Context

This part belongs to the Delevan 0819 series of fixed inductors. These components are characterized by their molded construction and axial leads, distinguishing them from surface mount variants within the broader product line.

Replacement Considerations

Cross-reference with other 0819 series parts such as 0819-20H or 0819-20G if different tolerance levels are required. Verify physical dimensions and pin compatibility when substituting.
