Procurement Notes

Verify the specific suffix 'Y' against official Bourns documentation to confirm reel packaging specifications. Ensure the voltage rating of 80V aligns with your system's operational limits. Confirm that the 800 mA current rating and 310 mOhm DCR meet your thermal and efficiency constraints before finalizing procurement.

Selection Notes

Select this component when AEC-Q200 compliance is mandatory for automotive projects. The 0905 package size suits space-constrained PCB layouts. Verify that the 1 mH inductance provides sufficient attenuation for the target noise frequencies. Ensure the operating temperature range covers the intended environmental conditions.

Part Context

This part belongs to the Bourns SRF0905A series of surface-mount power inductors. The series includes various models such as SRF0703A and SRR0745A, offering different inductance values and current ratings. These components are engineered for high-density mounting in modern electronic assemblies.

Replacement Considerations

Check for direct substitutes within the SRF0905A series or compatible AEC-Q200 chokes from other manufacturers. Verify pin compatibility and physical dimensions to ensure board fit. Compare electrical parameters like impedance and current rating to maintain circuit performance.
