Power over Ethernet (PoE) Transformers

Würth Elektronik PoE powered devices are for IEEE 802.3at, af, and bt applications

Image of Wurth Electronics Power over Ethernet (PoE) TransformersWürth Elektronik customers can choose between the WE-PoE, WE-PoEH, and WE-PoE+ power transformers depending on the power required by the powered device. All series use forward/flyback topology and are compatible with IEEE PoE standards.

With PoE according to IEEE 802.3af, currents of up to 350 mA per conductor pair are transmitted, whereas with PoE+ according to IEE 802.3at, currents up to 600 mA are possible. The voltage in both cases ranges between 48 V and 57 V. In the case of PoE connection, currents will be transmitted either isolated from the data signals on separate conductor pairs (this is only possible with 10/100 Base-T systems and only two pairs are used for signals), or they will be superimposed as PoE signals on top of the differential Ethernet signals.

WE-PoE: Power over Ethernet Transformer

  • WE-PoE series are flyback transformers designed for PoE PDs. These transformers feature input voltages from 36 V to 57 V, isolation voltage of 1.5 kVAC/1 min, and switching frequencies from 200 kHz to 500 kHz.

MID-PoE: Power over Ethernet Transformer

  • Power over Ethernet Transformers are small in size, cost-effective, and have low resistance. These transformers are optimized for PoE applications. The MID-PoE transformers feature a flat top for pick and place operation.

WE-PoE+: Power over Ethernet Plus Transformer

  • WE-PoE+ transformers are designed to meet 30 W PoE+ objectives of IEEE802.3at. These transformers feature a frequency range of 250 kHz to 400 kHz and an input voltage range of 36 V to 72 V.

WE-PoEH: Power over Ethernet High Power Transformer

  • Würth Elektronik WE-PoEH series are flyback or forward transformers with a standard footprint to EP13. These transformers offer different output voltages, have an input voltage range of 9 V or 33 V to 57 V, and switching frequencies from 200 kHz to 400 kHz. The WE-PoEH series feature an optimized core and bobbin design which allows 30% more power handling.

MID-POELT: Power over Ethernet Transformers for Linear Technology

  • PoE/ PoE+/PoE++ transformers were developed in partnership with Linear Technology. These transformers use low profile EP and EFD packages, have low leakage inductance, and output power between 13 W to 90 W. Output voltages are 5 V,12 V, or 24 V.

MID-POETI: Power Over Ethernet Transformers for Texas Instruments

  • MID-POETI transformers are small in size with a low profile allowing the components to be pick and placeable. The PoE transformers feature very low leakage inductance and low resistance. The MID-POETI series are available in EFD20, EP13, and ER19/4.8/15 packages.
