Fixed Inductors Procurement Notes

Verify the manufacturer part number SRP6540-1R5M against official Bourns documentation to confirm specifications. Ensure compatibility with surface-mount assembly processes. Check for any specific handling requirements related to the molded package. Confirm that the operating temperature range meets system design constraints.

Fixed Inductors Selection Notes

Select this component when a compact shielded inductor with high current capability is required. The 11 A rating suits applications demanding significant power handling. The 1.5 µH value is suitable for switching frequencies typical in modern power management ICs. Consider the 4 mm height profile for board space limitations.

Fixed Inductors Part Context

This part belongs to the SRP6540 series of shielded power inductors by Bourns. The series offers various inductance values and current ratings within the same 6540 footprint. It is categorized as a general-purpose fixed inductor suitable for broad electronic applications beyond specialized automotive or military grades.

Fixed Inductors Replacement Considerations

Direct substitutes must match the 1.5 µH inductance, 11 A current rating, and 7.2 x 6.5 x 4 mm dimensions. Verify equivalent DCR and shielding characteristics. Cross-reference with other manufacturers offering similar SMD shielded power inductors if availability is constrained.
