The **W2PE-52G-R/N** is a specific model of an **RJ45 Jack with Integrated Magnetics** (commonly known as a "MagJack"). These components are essential in networking hardware, combining a physical Ethernet port with the necessary isolation circuitry. --- ### 1. General Specifications This part is designed for high-speed data transmission and PCB mounting. Below are the primary characteristics: | Feature | Specification | | :--- | :--- | | **Connector Type** | RJ45 Female Jack | | **Configuration** | 1x1 Port (Single Port) | | **Ethernet Speed** | 10/100/1000 Base-T (Gigabit Ethernet) | | **Orientation** | Right Angle (Side Entry) | | **Shielding** | Metal Shielded (EMI Protection) | | **Mounting Type** | Through-Hole (THT) | --- ### 2. Internal Electronic Components The "Integrated Magnetics" aspect means several discrete components are housed inside the plastic casing of the jack: #### A. Isolation Transformers * **Purpose:** Provides galvanic isolation between the PHY (Physical Layer) chip and the external network cable. * **Protection:** Protects the internal circuitry from static electricity (ESD) and high-voltage surges on the Ethernet line. #### B. Common Mode Chokes * **Function:** Filters out high-frequency noise and Electromagnetic Interference (EMI) that could corrupt data signals. * **Importance:** Ensures compliance with FCC/CE emission standards. #### C. Termination Resistors (Bob Smith Termination) * **Usage:** Used to terminate unused wire pairs and minimize reflections, improving signal integrity over long distances. #### D. LEDs (Integrated) * **Green/Yellow:** Usually features built-in LEDs on the front face to indicate "Link" and "Activity" status. --- ### 3. Pinout and Mechanical Features * **Tab Direction:** Often "Tab Up" or "Tab Down" (specific to the R/N suffix variants), which dictates how the cable clip inserts into the port. * **Solder Pins:** Multiple signal pins for the Ethernet data lines, plus additional pins for the LEDs and shield grounding. ### 4. Typical Applications * **Network Interface Cards (NICs)** * **Industrial Routers and Switches** * **Embedded IoT Boards** (e.g., Raspberry Pi-style custom boards) * **Set-top Boxes** ---
