Arrays, Signal Transformers Procurement Notes

Verify the specific suffix 'HA' against the original design requirements, as it denotes the high-temperature variant with extended operating limits compared to standard versions. Confirm that the 1.83 A RMS current rating aligns with the thermal management strategy of the target application. Ensure the footprint matches the 7.6x7.6 mm package specifications during PCB layout review.

Arrays, Signal Transformers Selection Notes

Select this component when automotive certification (AEC-Q200) and high-temperature operation up to 150°C are mandatory. The dual-winding capability allows for flexible circuit topologies including coupled inductor designs. Compare the 119 mOhms DCR against efficiency targets and ensure the 15 µH inductance meets the ripple current requirements of the specific power stage.

Arrays, Signal Transformers Part Context

This part belongs to the SRF0703HA series of shielded power inductors manufactured by Bourns Inc. The series is designed for compact power electronics requiring robust performance in demanding environments. The HA designation specifically indicates enhanced thermal characteristics suitable for automotive under-the-hood or high-load applications where standard components may exceed their thermal limits.

Arrays, Signal Transformers Replacement Considerations

The SRF0703A-150M is a related model but lacks the high-temperature qualification and extended operating range of the HA variant. Verify if the lower temperature rating of the non-HA version is acceptable for the specific application environment before substitution.
