COILCRAFT Flyback/Forward Transformers for PoE

Coilcraft Flyback and Forward Transformers for PoE applications are compact, automotive-grade transformers for outputs up to 72W to support IEEE 802.3bt 4 pair PoE powered devices. 

The transformers are available with input voltage ranges from 9V to 57V and 33V to 57V and with output from 3.3V to 12V. The dual secondary outputs can be combined into a single, higher power output, with Flyback transformers rated for up to 12V and 1.5A, or 18W, per output, and Forward Mode transformers rated for up to 12V and 3A, or 36W, per output. They also offer an auxiliary 10V, 50mA output. 

Generally, flyback converters are ideal for smaller, lower-cost designs with high output voltage and a lower output current, while forward mode converters are ideal for applications requiring the highest efficiency. Coilcraft offers transformers optimized for both types of converters, allowing designers to optimize for efficiency, cost, and size. 

Coilcraft Flyback and Forward Transformers for PoE are AEC-Q200 Grade 1 qualified and rated for ambient temperatures from -40°C to +125°C. All models share the same compact package that weighs between 7.1g and 7.9g. This allows designers to reduce the size and weight of the convert and allows for design reuse at different output levels. To learn more about Coilcraft’s transformers for flyback and forward mode converters in PoE, visit Mouser.com.
