Procurement Notes
Verify the specific suffix against official manufacturer documentation to confirm exact electrical parameters, as suffixes often denote critical variations in tolerance or rating. Confirm RoHS compliance status directly with the supplier, as availability varies by production batch. Ensure the ordering quantity aligns with factory reel packaging requirements specified in the official datasheet.
Selection Notes
Select this component when a high-inductance value is required within a compact axial form factor for RF environments. The unshielded design necessitates careful layout consideration to minimize electromagnetic interference with adjacent traces. Verify that the operating current remains below the 39 mA maximum limit to prevent saturation or thermal issues.
Part Context
This part belongs to the Delevan 0819 series of fixed RF inductors. The series offers various inductance values in a standardized axial package. These components are engineered for reliability in radio frequency applications where stable performance and precise tolerance are critical for circuit integrity.
Replacement Considerations
Cross-reference with other Delevan 0819 series variants for different inductance values. Verify physical dimensions and pin compatibility before substituting with generic axial inductors to ensure proper fit and electrical performance in the existing RF circuit design.
