Dual-port PoE++ transformer

26 April 2022 Passive Components

Bourns’ Magnetics product division is introducing the new Model SM13143EL dual-port LAN 10/100/1000 Base-T PoE++ transformer for Ethernet applications. This part is IEEE 802.3bt Type 3 (also known as 4PPoE) compliant and PoE++ capable of up to 60 W with 700 mA DC balance current to support each channel, or 1400 mA DC balance current to support full channels.

The transformer’s operating temperature range is from -0ºC to +70ºC, with a 1,5 kVRMS isolation voltage. It features a DCR of 1400 mΩ maximum and a turns ratio of 1CT:1CT (±5%).
