Product Description
Product Overview
This Flyback PoE Transformer is designed for Power over Ethernet (PoE) applications, meeting IEEE 802.3at (PoE) standards. It operates efficiently in condition mode with a 37-57V input and features very low power loss due to its core design, supporting operation frequencies up to 300KHz. The transformer offers resistance to soldering heat, withstanding up to three 40-second reflows at +250C, and is rated Moisture Sensitivity Level (MSL) 1. It is suitable for industrial applications requiring reliable PoE power delivery.
