Procurement Notes
Verify the specific manufacturer part number against official API Delevan documentation to confirm electrical parameters and package type. Ensure compatibility with existing PCB footprints and thermal requirements before integration. Cross-reference datasheets for any updates regarding RoHS compliance or lifecycle status.
Selection Notes
Select this component based on its 680 nH inductance value and 395 mA current rating. Consider the unshielded design for applications requiring minimal magnetic interference coupling. Evaluate the 160 MHz self-resonant frequency to ensure suitability for the target RF bandwidth.
Part Context
This component belongs to the Delevan fixed inductor series, designed for general-purpose and RF applications. It utilizes a non-standard two-lead configuration for flexible mounting. The product line emphasizes reliability in electronic circuits requiring precise inductive characteristics.
Replacement Considerations
Consult official API Delevan substitution guides for verified alternative part numbers. Do not assume interchangeability with other manufacturers' components without verifying electrical specifications and physical dimensions.
