Procurement Notes
Verify the specific manufacturer datasheet to confirm RoHS compliance status and exact packaging quantities. Ensure that the axial lead configuration matches the target PCB footprint requirements. Cross-reference the maximum DC current rating against the actual operating conditions to prevent thermal issues during continuous operation.
Selection Notes
Select this component when a low-inductance value near 560 nH is required for high-frequency applications. The unshielded design may necessitate careful layout planning to minimize electromagnetic interference with adjacent sensitive traces. Consider the physical size constraints relative to other available axial inductors in the same series.
