Miniature AEC-Q200 Certified Power Inductors

The HA66 series of SMD power inductors has been introduced by TT Electronics for use in powerful applications where size is of great importance.

The compact construction of the low profile, low loss, ferrite-based inductors, combined with their AEC-2000 certification, is able to meet the performance demands required by high reliability and automotive applications.


The TT Electronics power inductors are highly suitable for use in DC-DC converters with high switching frequencies to a limit of 3 MHz, alongside EMI and low pass DC filters. Applications include:

  • Transportation
    • Power train
    • Engine control
    • Transmission control
    • LED driver
    • ABS braking systems
    • EPS
    • Radar systems
    • Camera control systems
  • Industrial
    • Automation systems
    • DC-DC converters


Specifications @ 25 °C

Variety: The series is made up of 38 inductors with a variety of package sizes, and with inductance ratings from 2.5 to 220 μH, DC resistances from 0.018 to 0.820 Ω and Irms values from 1.22 to 11.2 A.

Temperature: The inductors can be used in extreme temperatures, with parts having a temperature range for operation of -40 to +125 °C, and an ambient temperature maximum of  85 °C with maximum temperature rise of 40 °C.


(1) Isat is the saturation current which inductance rolls off approximately 35% from its initial (zero DC)

(2) Irms is the approximate current at which ∆T=40 °C


Compliance: The inductors are both RoHS compliant and AEC-Q200 certified, and are packed in embossed tape are reel in 1,000 or 2,000 units.
