TE Connectivity latest series Ethernet jacks integrate magnetics and Power over Ethernet (PoE), making them viable for industrial applications. The jacks are built using a flame-resistant (UL94-V0) liquid crystal plastic (LCP) that withstands high temperatures, which means they can be used with reflow soldering at 260°C, along with other components, simplifying assembly and reducing overall costs. The use of a three-wire choke prevents coil saturation and minimizes interference between power and signals.
Use of thick gold plating (0.76-µm over 1.27-µm nickel) on the contacts provides improved corrosion protection, reducing the risk of contact problems over time when the jacks are used in harsh environments. The jacks have an extended operating temperature range, stretching from minus 40°C to 85°C, making them viable for a very broad spectrum of industrial applications.
