Modular connectors, including jacks with magnetics, are an integral part of today\'s communication technology. The ARJP11A-MASA-B-A-EMU2 is a great example of these modular connectors. It is well suited for Ethernet applications where good common-mode isolation and an enhanced crosstalk performance are required. It is also commonly used in embedded systems, such as Ethernet switches, routers, firewalls, access points, and so on.

The ARJP11A-MASA-B-A-EMU2 utilizes an innovative packaging method to minimize crosstalk and improve channel isolation in Ethernet applications. Its magnetics, arranged in a single row, are designed to ensure the maximum possible signal integrity and system performance. The module consists of two halves, one linear half comprising MC0 through MC15 pins, and the other rotary half bearing a rotary barrel. Interconnection between these two halves is enabled via two common-mode chokes that provide galvanic isolation of the live pins in the mating pairs. The ARJP11A-MASA-B-A-EMU2 also contains a ground lug that ensures an uninterrupted ground path between internal components and the PCB.

In terms of working principle, the ARJP11A-MASA-B-A-EMU2 is first mated with a mating connector on one end. This mating connector, when it touches the live pins of the ARJP11A-MASA-B-A-EMU 2, will create a loop of alternating current (AC) between the two pins. This current is then blocked by the common-mode chokes that provide galvanic isolation between the pins. As a result, different electrical noise signals are prevented from traveling along the signal line and influencing the system performance.

The ARJP11A-MASA-B-A-EMU2 also provides a large contact area for establishing reliable connections. This helps reduce misalignment issues, while the shared impedance feature ensures fast circuit switching times and low insertion losses. Additionally, the extra-thick terminals prolong the connectors’ lifespan and help them withstand voltage spikes. Finally, the high-performance contacts ensure reliable long-term connections.

In today’s world of Ethernet applications, improving signal integrity has become an essential part of successful system performance. Modular connectors with magnetics, such as the ARJP11A-MASA-B-A-EMU2, are available to help achieve this goal. Through the minimal crosstalk ensured by its magnetics, high contact area, shared impedance, and high-performance contacts, the ARJP11A-MASA-B-A-EMU2 can be a great way to improve signal performance while avoiding misalignment issues.
