The CONEC RJ45 Magnetic Modular Jack (RJ45 MM-Jack) connector series has been specifically designed for use with 10Base-T and 100Base-Tx LAN Ethernet applications, as defined by IEEE 802.3u Standard Organization. This series of connector is widely specified for use in telecommunications and data transmission. It is an ideal solution to suppress EMI and common mode noise in a wide range of Ethernet networking applications, such as network cards, hubs, concentrators, motherboards, bridges, router switches and point to point links. The CONEC RJ45 MM-Jack provides excellent common mode and EMI noise suppression that delivers reliable and enhanced filtering performance.

Construction of RJ45 MM-Jack
Available in single port, 2, 4, 6, 8 ports and in Through Hole or SMT versions. Each port integrates a 10/100Base-Tx Magnetic Module, with one of the following two different configurations:
- Two isolation transformers and two common mode chokes
or
- Two isolation transformers and common mode chokes as well as an additional shunt choke in the    transmission channel
4 x 75W resistors and a 1000pF/2kv capacitor is also integrated into each port. Two of the resistors are connected to the centre tap of the transformers. One of the resistors is connected to unused pins #4 & #5 of connector. The last resistor is connected to unused pins #7 & #8 of connector. All resistors are then connected to the 1000pF/2kv capacitor, this provides a low impedance ground path that reduces common mode noise. LEDs are also available as an option for the RJ45 MM-Jack series.
UL/cUL Approved and Telcordia Qualified
Whole RJ45 MM-Jack series is UL/cUL (File No. E202784) approved and Telcordia Qualified.
- UL File No. E202784
- Telcordia Report of CONEC RJ45 MM-Jack Qualified and Reliability Analysis
Meets IEEE Standard Requirements
Fully compliant with IEEE 802.3 and ANSI X3.263 Standards including the Min. 350uH OCL with 8mA DC bias and 1500V(RMS) isolation voltage requirements.
Saving the Board "Real Estate"
The integration of the Magnetic Module and several discrete components into the RJ45 MM-Jack save valuable board space. The use of standard RJ45 connectors would require additional space on the customer board for those components.
Provides better EMC
EMI susceptibility radiated emission and near field noise coupling is dramatically reduced as the traces between the connector and LAN transceiver IC are minimized through this integration solution. Moreover, the internal layout of the components reduce cross talk and optimize PCB trace routing.
Helps system to pass the low emission requirements

Emission requirements apply to the system not to the components. CONEC RJ45 MM-Jack helps system to achieve the low emission requirement, since it provides excellent common mode and EMI noise suppression.
