Arrays, Signal Transformers Procurement Notes

Verify the specific suffix 'M' corresponds to the required tape and reel packaging format as indicated by distributor listings. Confirm that the AEC-Q200 certification meets your specific automotive quality standards. Ensure the 0703 package footprint matches your PCB layout constraints precisely. Cross-reference the datasheet for thermal derating curves if operating near the maximum temperature limit.

Arrays, Signal Transformers Selection Notes

Select this component when a compact, shielded dual-inductor solution is needed for automotive or industrial power stages. The 68 µH parallel value suits moderate current applications around 890 mA. Consider the series configuration if higher inductance is required at lower current levels. The low profile fits tight vertical clearance requirements compared to larger chokes.

Arrays, Signal Transformers Part Context

This part belongs to the Bourns SRF0703A series of dual-winding shielded power inductors. The series provides various inductance values ranging from 8.2 µH to 600 µH.
