The **W2CE-5A3-R** is a specific part number typically associated with **RJ45 Modular Jacks** integrated with internal magnetics (often referred to as **MagJacks**). These components are essential in networking hardware to provide physical connectivity and electrical isolation. --- ### 1. Technical Specifications The following table outlines the typical electrical and physical characteristics of this series: | Parameter | Specification | | :--- | :--- | | **Component Type** | RJ45 Connector with Integrated Magnetics | | **Port Configuration** | Single Port (1x1), Tab-Down | | **Speed/Performance** | 10/100 Base-T (Fast Ethernet) | | **LED Configuration** | Typically Green/Yellow (Bi-color or dual) | | **Shielding** | Metal Shield with EMI fingers | | **Mounting Type** | Through-Hole (THT), Right Angle | | **Operating Temp** | -40°C to +85°C (Industrial Grade) | --- ### 2. Key Internal Components The "Integrated" nature of the W2CE-5A3-R means it contains more than just plastic and copper. Inside the housing, you will find: * **Isolation Transformer:** Protects the internal circuitry (PHY chip) from high-voltage spikes on the network cable. * **Common Mode Chokes:** Used for EMI (Electromagnetic Interference) suppression to ensure the device meets regulatory standards (like FCC or CE). * **LEDs:** Integrated indicators for "Link" and "Activity" status, saving PCB space. * **Termination Resistors/Capacitors:** Often includes a "Bob Smith" termination to reduce common-mode noise. --- ### 3. Pinout & Schematic Overview While specific pinouts can vary by manufacturer, the W2CE series generally follows the standard Ethernet MDI interface: ```text [RJ45 Side] [PCB Side] 1. TX+ ----------> TD+ 2. TX- ----------> TD- 3. RX+ ----------> RD+ 6. RX- ----------> RD- 4,5,7,8 ----------> Termination/GND ``` --- ### 4. Applications This part is commonly used in the following devices: * **Embedded Systems:** Single-board computers (SBCs). * **Industrial Automation:** PLCs and industrial gateways. * **Networking Gear:** Routers, switches, and network interface cards (NICs). * **IoT Devices:** Ethernet-connected sensors and controllers. ---
