Procurement Notes

Verify the specific suffix 'YH' against the manufacturer's official datasheet to confirm exact electrical tolerances and packaging specifications. Ensure the component meets AEC-Q200 requirements if intended for automotive applications, as compliance details should be confirmed via official documentation rather than distributor summaries.

Selection Notes

Select this component when space constraints require a 4.5mm x 3.2mm footprint. Choose based on the required 100 µH inductance and 200mA current rating. Consider the 1.5 Ohm DC resistance for power loss calculations. Verify thermal performance needs against the -55°C to +150°C operating range.

Part Context

This part belongs to the SRF4530A series of common mode chokes from Bourns. The series is characterized by shielded designs suitable for high-density PCB layouts. These components are engineered for signal integrity protection in electronic circuits requiring effective noise attenuation.

Replacement Considerations

Consult official substitution guides for compatible parts. Cross-reference inductance values, current ratings, and physical dimensions to ensure functional equivalence without modifying the circuit layout.
