Procurement Notes

Verify the specific suffix requirements against the manufacturer datasheet to ensure correct packaging and tolerance specifications. Confirm that the maximum DC current rating of 27 mA aligns with the operational load conditions of the target application to prevent saturation or thermal issues during procurement validation.

Selection Notes

Select this component when a precise 680 µH value is required in a compact axial form factor. The unshielded design necessitates careful layout planning to avoid coupling with sensitive traces. Ensure the operating frequency remains below the 4.5 MHz self-resonant point for effective inductive behavior.

Part Context

This part belongs to the Delevan 0819 series of RF inductors, characterized by molded coils and axial leads. The series offers various inductance values optimized for radio frequency applications, providing a balance between electrical performance and physical size for dense electronic assemblies.

Replacement Considerations

Cross-reference with API Delevan part numbers within the same 0819 series family for equivalent electrical parameters. Verify mechanical dimensions and pin compatibility before substituting with generic axial inductors.
