As the electrification of the automotive progresses, the demand for motor generators is on the rise. There is also a trend towards integration of electric motors and inverters, and the requirements with regard to compact dimensions and resistance against heat and vibrations are becoming ever more severe, while high reliability is also an important factor. In some cases, wiring inductance can lead to high surge voltages which requires countermeasures such as suitable wiring design and snubber capacitors. At the same time, noise countermeasures are also essential.

Here are S-parameters where products in the ALT series and common mode filters/chokes are combined in the recommended ways for use with 1000BASE-T.

Conventional devices with hand-laid windings suffer from various problems such as uneven characteristics due to manufacturing tolerances. By contrast, the new pulse transformers from TDK offer excellent uniformity and provide comparable performance as existing products at a much smaller footprint. The ALT series is bound to become a new reference in this field.
