Category 5e compact modular jacks

14 August 2002 Interconnection

Category 5e compact modular jacks from Molex provide a lower profile than the standard modjack for maximum PCB stackability in 2, 3 and 4 port variations. Applications for these modular jacks include networking equipment such as hubs, routers and switches. They also meet GB Ethernet, Fast Ethernet and Ethernet speeds while conforming to Compact PCI, Eurocard and Common Mezzanine Card Standards.

These modjacks measure 9,53 mm from the top of the PCB to the top of the jack, allowing for optimal board stacking. This is accomplished by allowing the bottom of the modjack to sit flush with the bottom of the PCB, while adhering to the 2 mm creepage and clearance specification. The reduction in cross talk means the RJ-45 configuration provides Category 5e performance for GB Ethernet applications with near end cross talk (NEXT) loss greater than 43 dB at 100 MHz.

Enhanced panel grounding metal tabs on shielded versions offer superior ground path to the panel or metal bezel for maximum shielding performance. Internal grounding tabs complete the circuit to ground for shielded cable and plug applications. Three shield options are available: standard; with enhanced grounding tabs, and bezel ground tabs.

With an operating temperature of -40 to +85°C, they are available in through-hole styles for wave soldering or high temperature re-flow soldering and are UL and CSA approved.
