The new single-port MaxJack RJ45 connectors from Erni, with a straight design and integrated magnetic filter components, are configured for IEEE 802.3-compliant applications, such as gigabit ethernet or poe controller simplifies PD design" target=_blank>power-over-ethernet (PoE).

By integrating the magnetic components, which would otherwise be surface mounted on the PCB, MaxJack reduces interference and saves PCB space, said the press release. These fully shielded connectors 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 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 also only slightly larger, and it can be aligned on a grid. According to the company, the small, compact dimensions make it possible to keep the circuit paths short and thus achieve very good signal integrity. Return loss is specified at -3dB over the frequency range of 1MHz to 125MHz, which makes it possible to extend port distances beyond the 100m limit that is recommended by the IEEE, said Erni.

Priced at $2 each in volume quantities, the MaxJack connectors are available in single-port and multi-port versions in ganged and stacked configurations.
