AEC-Q200 Compliant Power Inductors For Demanding Automotive Applications

Interior of a modern car

Compact, surface mount power inductors from TT Electronics operate in demanding automotive environments 

TT Electronics has unveiled the HA72L series surface-mount power inductors for use in high power density applications where size is critical. Their compact design, together with their AEC-Q200 certification provide the performance and reliability levels that many high-reliability automotive applications demand. Such applications include high-efficiency DC/DC converters using high switching frequencies to 3MHz as well as EMI and low pass DC ripple filters in high-temperature environments where these moulded inductors deliver clean power in a small, lightweight surface mount package.

Main applications for the HA72L series are LED drivers, automotive LCD/LED displays, engine and transmission control units, diesel injection drivers, DC/DC converters for entertainment/navigation systems, noise suppression for motors, braking, windshield wipers, power steering, seats and mirrors, heating and ventilation blowers.


They are also good for use in industrial applications including switch mode power supplies, automation systems and DC/DC converters.

New HA72L series AEC-Q200 compliant compact inductors

TT Electronics’ rugged HA72L is magnetically shielded, can handle high transient inrush current spikes and has been designed for a maximum operating temperature range of -55 to +155 °C.

The inductors come in sizes ranging from from 4 x 4 up to 17 x 17mm, featuring an inductance range from 0.1 up to 100uH, a heating current range from 1.2 up to 60A, and a frequency range from 1kHz up to 3MHz. All components are halogen and lead-free, RoHS compliant and AEC-Q200 certified.
