SRF1280A-1R0Y

Overview

The Bourns SRF1280A-1R0Y is a dual-winding shielded power inductor from the SRF1280A series. It features an inductance of 1 µH with a tolerance of ±30%. The component has a DC resistance (DCR) of 6.7 mΩ and supports a current rating of 15.5 A. It utilizes a shielded construction to minimize electromagnetic interference. The package dimensions are 12.50 mm x 12.50 mm x 8.00 mm, suitable for surface mount applications requiring high current handling.

Feature Summary

• Dual-winding configuration allows flexible circuit integration
• Shielded design reduces magnetic field emissions
• High current capability for power delivery networks
• Automotive grade reliability compliant with AEC-Q200

Applications

• Parallel or series connected inductor arrays
• Transformer applications
• Dual-inductor configurations
• High current power supply stages

Procurement Notes

Verify the specific suffix 'Y' indicates the tape and reel packaging format when ordering. Confirm that the dual-winding nature aligns with the schematic requirements, as this component functions as an array rather than a single coil. Ensure the PCB footprint matches the 12.50mm x 12.50mm outline. Check for any specific handling instructions related to the shielded core material during assembly processes.

Selection Notes

Select this part when a compact dual-coil solution is required for high-current applications. The 1 µH value and low DCR make it suitable for efficient power conversion stages. Consider the physical height of 8.00 mm against board clearance constraints. The AEC-Q200 qualification makes it appropriate for automotive environments where robustness is critical compared to standard industrial components.

Part Context

This component belongs to the SRF1280A series of dual-winding shielded power inductors by Bourns. These inductors are designed for versatility, allowing users to configure them in parallel, series, or as independent dual inductors. The series is characterized by its ability to handle significant current while maintaining a small footprint, addressing space constraints in modern electronic designs.

Replacement Considerations

Direct substitutes within the same series include other values such as SRF1280A-6R8Y. Verify pin compatibility and electrical parameters before swapping. No alternative part numbers are explicitly confirmed as direct replacements in the provided documentation.
