The Advantages of Integrated Connector Modules

Filed under: General

A MagJack, or Integrated Connector Module (ICM for short) is a combination of up to 10 discrete components. They include: The RJ45 connector, the impedance matching transformers, 2 LED s, 4 termination resistors, 1 high voltage capacitor, and often common modes chokes as well.

Today s ethernet or LAN hardware engineers have two ways to lay these components out on their boards. First, they can do it discretely. That is, they can lay out each of the parts I mentioned individually on the board, and this is the way it was typically done up until the late 1990 s. The second, and I believe the better way, to attack this problem, is to use a MagJack, or Integrated Connector Module, from BEL.
