The **W2PP-229R-R** is a specific type of electronic connector, commonly classified as a **Modular Jack** or **RJ45 connector**. This specific part number is typically associated with manufacturers like **Walsin** or **Win Win**, often used in networking hardware. --- ### 1. Technical Specifications Below are the primary electronic and mechanical characteristics of the W2PP-229R-R: | Feature | Specification | | :--- | :--- | | **Component Type** | RJ45 Modular Jack | | **Orientation** | Right Angle (Horizontal) | | **Positions/Contacts** | 8P8C (8 Positions, 8 Contacts) | | **Shielding** | Shielded (Metal Shell) | | **Mounting Type** | Through-Hole (THT) | | **LED Indicators** | Often includes integrated LEDs (typically Green/Yellow) | | **Tab Direction** | Tab Down | --- ### 2. Key Electronic Components & Materials The assembly of the W2PP-229R-R consists of several critical sub-parts: 1. **Contacts (Pins):** * Made of Copper Alloy. * Plated with **Gold** (usually 3µ" to 50µ") over Nickel to ensure high conductivity and prevent oxidation. 2. **Shielding Shell:** * A brass or copper alloy shell plated with Tin or Nickel. * **Function:** Acts as a Faraday cage to protect signal integrity from Electromagnetic Interference (EMI). 3. **Insulator/Housing:** * Thermoplastic (usually UL94V-0 rated). * **Function:** Provides high dielectric strength to prevent short-circuiting between pins. 4. **Integrated Magnetics (Optional but common in this series):** * Contains small wire-wound transformers (common mode chokes). * **Function:** Provides signal conditioning, impedance matching, and high-voltage isolation (1500V AC). --- ### 3. Applications The W2PP-229R-R is designed for high-speed data transmission environments, including: * **Network Interface Cards (NICs):** Found in PCs and servers. * **Routers & Switches:** Used for LAN port connectivity. * **Industrial Automation:** Connecting PLCs to Ethernet networks. * **Embedded Systems:** For IoT devices requiring a wired internet connection. --- ### 4. PCB Footprint Considerations When designing a PCB for this part, engineers must account for: * **Solder Tail Length:** Usually around 3.0mm to 3.5mm for standard PCB thicknesses. * **Mechanical Pegs:** Plastic posts on the bottom to provide structural stability during cable insertion/extraction. * **Grounding Tabs:** The shield often has "fingers" that must make contact with the metal chassis for proper ESD protection.
