Procurement Notes
Verify the specific ordering suffix against official API Delevan documentation to ensure correct tolerance and packaging specifications. Confirm RoHS compliance status and environmental declarations prior to integration. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability. Ensure the selected variant matches the required electrical parameters for the target application.
Selection Notes
Select this component when precise 120 µH inductance is required for RF signal paths. The unshielded design necessitates careful layout consideration to prevent magnetic coupling with adjacent components. Verify that the 54.5 mA current rating exceeds the maximum expected operational load. Ensure the axial package dimensions fit within the designated PCB footprint constraints.
Part Context
This component belongs to the Delevan 0819 series of fixed RF inductors. The series utilizes molded unshielded coils optimized for radio frequency performance. These inductors are engineered for stability and consistent electrical characteristics across varying environmental conditions. The axial form factor facilitates automated insertion and reliable soldering on printed circuit boards.
Replacement Considerations
Consult official substitution guides for equivalent inductance values. Verify compatibility regarding physical dimensions, pin spacing, and thermal ratings. Ensure alternative components meet the same RF performance criteria and tolerance requirements.
