Procurement Notes
Verify the specific manufacturer part number against official datasheets to ensure compatibility with design requirements. Confirm RoHS compliance status and lead-free characteristics prior to integration. Check for any obsolescence notices or product change notifications that may affect long-term supply chain stability and component availability.
Selection Notes
Select this component for applications requiring precise inductance values in radio frequency environments. Consider the unshielded nature when layout proximity to other sensitive components is critical. Evaluate the 210 mA current limit against peak operational loads to prevent saturation. Ensure the physical footprint matches the target PCB land pattern specifications.
Part Context
This component belongs to the API Delevan fixed inductor family, specifically designed for surface-mount technology. It serves as a passive energy storage element within electronic circuits, providing inductive reactance at specific frequencies. The series is characterized by compact dimensions suitable for space-constrained modern electronics designs.
Replacement Considerations
Consult official manufacturer substitution guides for verified equivalent part numbers. Cross-reference electrical parameters such as inductance, tolerance, and current rating to ensure functional compatibility without altering circuit behavior.
