Fixed Inductors Procurement Notes

Verify the specific manufacturer part number against official Bourns documentation to ensure accuracy. Confirm that the required electrical parameters, such as saturation current and DC resistance, align with the target circuit design requirements before finalizing procurement decisions.

Fixed Inductors Selection Notes

Select this component when a shielded inductor with moderate inductance and low current handling is required. Consider the 1.5 Ohm DCR impact on efficiency. Ensure the PCB footprint matches the non-standard SMD 1240 package dimensions provided in the mechanical drawings.

Fixed Inductors Part Context

This component belongs to the SRR1240 series of shielded SMD power inductors by Bourns Inc. The series offers various inductance values optimized for surface-mount assembly. These inductors are designed for applications requiring compact size and reliable magnetic shielding in power electronics.

Fixed Inductors Replacement Considerations

Direct substitutes must match the 560 µH value, 1240 package size, and similar current ratings. Verify compatibility with existing PCB footprints and thermal management strategies when considering alternative manufacturers or series.
