The **M2PP-94R-R** is a specific part number belonging to a series of high-performance **Multi-Gigabit MagJack® Integrated Connector Modules (ICMs)** manufactured by **Bel Fuse / TRP Connector**. These components are essential in networking hardware, combining a standard RJ45 connector with the internal magnetic components required for signal conditioning and isolation. --- ### 1. Key Technical Specifications | Feature | Specification | |:---|:---| | **Connector Type** | RJ45 Female | | **Data Rate Support** | 2.5GBase-T / 5GBase-T (Multi-Gigabit) | | **Port Configuration** | 1x1 (Single Port) | | **Orientation** | Right Angle / Horizontal (Tab Down) | | **Shielding** | Metal Shielded (EMI protection) | | **Mounting Type** | Through-Hole | | **LED Indicators** | No (R-R variant typically signifies non-LED or specific wiring) | --- ### 2. Internal Electronic Components The "MagJack" designation means this is not just a plastic jack; it contains a tiny PCB inside with the following electronic parts: * **Isolation Transformers:** Provides 1500Vrms isolation between the cable side and the PHY (Physical Layer chip) side to protect the device from surges. * **Common Mode Chokes:** These suppress electromagnetic interference (EMI) and noise on the differential signal lines. * **Termination Resistors:** Typically 75-ohm resistors used to match impedance and reduce signal reflections (often referred to as Bob Smith Termination). * **High-Voltage Capacitors:** Usually 1000pF to 2000pF capacitors used for decoupling and shunting high-frequency noise to the ground shield. --- ### 3. Application Areas The M2PP series is designed for modern high-bandwidth hardware where standard 1Gbps speeds are insufficient: 1. **Network Switches & Routers:** Specifically for Multi-Gigabit ports. 2. **Base Stations:** Cellular and wireless backhaul equipment. 3. **Industrial Controllers:** High-speed data acquisition systems. 4. **Servers:** High-density computing environments requiring 2.5G or 5G connectivity. --- ### 4.
