Procurement Notes
Verify the specific manufacturer designation, as API Delevan assets have been acquired by other entities. Confirm RoHS compliance status and lead content details against current official datasheets, as historical records indicate mixed compliance levels for this series. Ensure the ordering suffix matches the required packaging quantity and terminal finish specifications.
Selection Notes
Select this component for applications requiring moderate inductance values with tight tolerance requirements. The unshielded design necessitates careful layout planning to minimize electromagnetic interference with adjacent components. Verify that the operating current remains below the 310 mA limit to prevent saturation or thermal issues.
Part Context
This part belongs to the Delevan 0819 series of fixed RF inductors. These components are characterized by their cylindrical molded bodies and axial leads, offering a robust solution for through-hole PCB assembly. The series covers a range of inductance values tailored for radio frequency and general electronic applications.
Replacement Considerations
Cross-reference with other axial leaded RF inductors from manufacturers such as Bourns or Coilcraft. Ensure equivalent inductance, current rating, and physical dimensions are maintained. Verify that substitute parts offer comparable self-resonant frequency characteristics.
