TT Electronics inductors target reliability for automotive use

HM73E-10 SMT miniature power inductors from TT Electronics

The HM73E-10 SMT miniature power inductors from TT Electronics are targeted at high reliability applications in the automotive industry. The inductors are suitable for high efficiency DC-DC applications where size is critical.

The AEC-Q200 certified inductors are mechanically robust, magnetically shielded and have been designed to increase the inductance value and high saturation current for better performance. They also have a lower DC resistance and an improved, lower temperature rise performance than their predecessors.

Six models are available embracing current ratings from 15 to 65A and they can operate over a temperature range of -50 to +155˚C.

At 100kHZ, inductance ratings range from 3.76µH for the smallest inductor to 0.19µH for the largest, 65A rated unit. All have an 11.5 by 10.6mm footprint, with a height of 5.9mm.

RoHS compliant, the inductors will be of interest to system designers, component engineers and design engineers for use in automotive powertrains, engine and transmission control, hybrid electric vehicles, start-and-stop systems and electric power steering.

Industrial applications include switch mode power supplies, automation systems and DC-DC converters.
