Procurement Notes

Verify the specific suffix and manufacturer documentation to confirm exact electrical tolerances and package variations. Ensure compatibility with automated placement equipment regarding the surface mount footprint. Cross-reference official datasheets for precise thermal derating curves and saturation current limits before finalizing procurement specifications.

Selection Notes

Select this component when space-constrained designs require high inductance values in a small 0905 footprint. Consider the 300 mA current rating against peak load requirements to prevent saturation. Verify that the 5 kOhm impedance at 300 kHz aligns with the target noise frequency spectrum for effective filtering.

Part Context

This part belongs to the Bourns SRF0905A series of surface-mount common mode chokes. The series utilizes ferrite toroid technology to achieve high inductance density. These components are engineered for applications requiring robust EMI filtering in limited board real estate while maintaining automotive-grade durability.

Replacement Considerations

Check for direct substitutes within the SRF0905A series such as SRF0905A-471Y or SRF0905A-251Y if different inductance values are acceptable. Ensure any replacement maintains the same 0905 footprint and AEC-Q200 qualification status for automotive compliance.
