Integrated Magnetic Filter Components for PoE

As part of its MaxJack family, ERNI has introduced RJ45 connectors that satisfy even the highest demands in modern data networks. The new single-port MaxJack, with a straight design and integrated magnetic filter components, is configured for IEEE 802.3-compliant applications, such as Gigabit Ethernet or Power over Ethernet (PoE). Thus, the new RJ45 MaxJack connectors are aimed at high-speed telecommunications and data communications applications in data storage devices, personal computers, network printers and peripheral equipment, as well as in increasing numbers of industrial applications.

By integrating the magnetic components that would otherwise be surface mounted on the printed circuit board (PCB), MaxJack reduces interference and saves PCB space. These fully shielded MaxJack products can be customized to match specific designs and are available for Ethernet data rates (10/100 Base TX, 10/100/1000 Base T). Further options include LEDs and enhanced ESD protection (Telcordia Lightning Strike Protection).

The angled RJ45-compatible connectors from ERNI are based on a patented design that makes it possible to integrate the filter elements without changing the size of the jack housing. The new straight version is only slightly larger and can be aligned on a grid. The small, compact dimensions make it possible to keep the circuit paths short and thus achieve good signal integrity. With respect to noise, the MaxJack series complies with the IEEE802.3ab specifications. Return loss is specified at -3 dB over the frequency range from 1 MHz to 125 MHz. This makes it possible to extend port distances beyond the 100-meter limit that is recommended by the IEEE. The MaxJack connectors are available in single-port and multi-port versions in ganged and stacked configurations.

The MaxJack connectors are available immediately at $ 2.00 each in volume.
