Mini-PCI right angle modular jacks
15 August 2001
Interconnection
The Mini-PCI compliant inverted right-angle modular jacks (modjacks) from Molex offer signal reliability and flexibility. The modjacks provide a platform to the emerging Mini-PCI standard for LANs, notebook computers, modems, docking stations, NetPCs and set-top boxes.
Available with or without lightpipes in shielded and unshielded versions, a plug latch on top is provided for easy mating and disengaging. Made for both RJ-11 and RJ-45 configurations, these modjacks comply with FCC gold plating requirements, intermate with most FCC 68 modular plugs and are UL and CSA approved. The short leads of this bottom contact design reduce crosstalk, as well as the 'antenna' effect, minimising susceptibility to radiated interference carried across transmission lines. The reduction in crosstalk means the RJ-45 configuration provides Cat 5 performance for fast Ethernet applications with near end crosstalk (NEXT) loss greater than 40 dB at 100 Mbs/100 MHz with pairs 1,2 and 3,6.
The lightpipe version directs light from PCB-mounted LEDs to the modjack front to indicate system activity or status. On the shielded modjack version, enhanced panel grounding metal tabs provide superior ground path to panel or bracket resulting in optimal shielding effectiveness.
