“The integrated magnetic elements of our new Ethernet connectors eliminate the need for traces on the analog portion of the board circuitry, while still meeting the system’s transmission requirements,” explains Ruud van den Brink, TE’s product manager for the new Ethernet connectors. “Furthermore, by complying with the IEEE 802.3 (PoE+) standard, these connectors can be used to power devices up to 25.5 W per port.”
The Ethernet connectors are made from flame-retardant (UL94 V-0) and high-temperature-resistant liquid crystal plastic (LCP), meaning they can be reflow-soldered at 260°C, along with other components, simplifying assembly and reducing overall costs. The use of a three-wire choke coil prevents coil saturation and minimizes interference between power and signals.
The thick gold plating (0.76 µm compared to 1.27 µm nickel) on the contacts provides enhanced corrosion protection, reducing the risk of contact problems over time when the connectors are used in harsh environments. The connectors have a wide operating temperature range, from -40°C to 85°C, making them suitable for a broad spectrum of industrial applications.
