Procurement Notes

Verify the specific part number suffix against official manufacturer documentation to confirm exact electrical tolerances and packaging configurations. Ensure compatibility with existing PCB footprints and thermal management requirements before finalizing procurement decisions based on verified datasheet specifications.

Selection Notes

Select this component for applications requiring low-inductance RF filtering or impedance matching where unshielded performance is acceptable. Consider the 510 mA current rating and 250 MHz self-resonant frequency limits when designing high-frequency signal paths to ensure stable operation within specified parameters.

Part Context

This component belongs to the 0819 series of fixed inductors manufactured by Delevan. The series offers various inductance values in a consistent axial package format, providing designers with standardized options for through-hole mounting in electronic assemblies requiring precise RF characteristics.

Replacement Considerations

Consult official substitution guides for equivalent axial RF inductors from other manufacturers if availability is constrained. Verify that any substitute matches the 560 nH value, 3% tolerance, and physical dimensions to maintain circuit integrity.
