Molex's New Modular Jacks

With Lightpipes Reduce

EMI/RFI Over 50%

Molex Incorporated introduces a new inverted right angle

modular jack with lightpipes that significantly reduces the

noise created by the "antenna" effect of LED leads incorporated

into the modular jack. The lightpipes direct the light emitted

from the LEDs mounted on the PC board rather than using

conventional LEDs mounted in the modular jacks. This design

maintains signal integrity since there is no interference from

LED leads. Because the LEDs are located on the PC board, you

can select the colors used for the LEDs. Unlike typical LED

modular jacks, you are not restricted to the standard green,

yellow or orange LEDs. The combination of PC board mounted

LEDs and lightpipes results in less noise being radiated though

transmission lines.

The inverted modular jacks with lightpipes are available in

through hole styles for wave soldering or a high temperature

version for reflow soldering. The high-temperature version

maintains performance at a +260°C reflow soldering

temperature for 1 minute without deforming the modular jack

or lightpipe. Shielded and unshielded offerings are available

for both RJ11 and RJ45 configurations for the standard

through hole version and a shielded modular jack is offered

with the high temperature lightpipes.

Features and Benefits

s

Signal integrity remains high due to no interference from

LED leads

s

Lightpipes reduce the electronic noise from LEDs by as

much as 50%

s

The inverted RJ45 Lightpipe modular jack provides Cate-

gory 5 performance for fast Ethernet applications

s

Meets FCC 68.5 specification when plating selection is 50µ"

of gold (30 and 15µ" of gold plating are also available)

s

Each Molex modular jack is 100% electronically tested to

detect possible shorting conditions before the product is

shipped

s

Plug latch on top of jack provides easy thumb depression

for mating and unmating

s

Inventory can be reduced by not stocking modjacks with

different colored LEDs
