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.

TDK Corporation presents a new series of EPCOS transformers designed for an output of up to 60 W, which are therefore suitable for PoE++ according to IEEE 802.3bt. The new B82806D0060A** series comprises four types with different turns ratios for output voltages of 3.3 V, 5 V, 12 V, and 24 V.

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.
