Fixed Inductors Procurement Notes

Verify that the specific suffix 'HA' corresponds to the required high-temperature or automotive grade variant as defined by the manufacturer's official documentation. Confirm that the 47 µH inductance value aligns with the target circuit design requirements before procurement. Ensure compliance with RoHS and halogen-free specifications if mandated by the end-product regulations.

Fixed Inductors Selection Notes

Select this component when space-constrained automotive designs require shielded inductors with low radiation. The 7.3mm footprint suits compact layouts. Verify that the 0.85A current rating exceeds the application's peak current demands. Consider the 320mΩ DCR impact on efficiency. Ensure the 125°C rating matches the thermal environment.

Fixed Inductors Part Context

This part belongs to the Bourns SRR0735HA series of shielded power inductors. The series is characterized by its small form factor and suitability for high-density PCB layouts. It is distinct from the standard SRR0735A series by its specific automotive-grade qualifications and performance characteristics tailored for demanding environments.

Fixed Inductors Replacement Considerations

Direct substitutes include other Bourns SMD power inductors with similar 7.3x7.3mm footprints and 47µH values, such as the SRR0735A-470M, provided the specific HA-series automotive qualifications are not strictly required. Cross-reference DCR and current ratings carefully.
