Certified Inductors Hit The Road

AEC-Q200 certified and specified for operation from -55°C to +155°C, TT Electronics’ HA74 series surface-mount power inductors combine a low profile, small footprint, and 3-MHz switching capability. Groomed for use in dc/dc converters, the series suits automotive use cases including the latest generation of high-density converters and pi filters for Advanced Driver Assistance System (ADAS) controllers. The shielded inductors ensure low EMI and are highly resistant to corrosion.


Maximum height is 2.05 mm and the components measure 5.5 mm x 5.5 mm footprint. Current ratings are up to 2.9A and dc resistance is down to 74 mΩ. The complete HA74 family comprises 10 parts covering standard inductance values from 4.7 µH to 33 µH and current ratings from 1.2A to 2.9A. Semi-custom inductors conforming to individual customer specifications are also available via special order. For further technical information, peruse the HA74 datasheet.
