The **M5RJ18UPJ-R** is a specific electronic component, typically categorized as a **Modular Jack (RJ45)** connector. These parts are fundamental in networking hardware for Ethernet connectivity. Below is a detailed breakdown of its electronic and mechanical specifications. ### 1. Component Overview The M5RJ18UPJ-R is a Right-Angle, Shielded, Tab-Up RJ45 connector. It is designed for Through-Hole mounting on Printed Circuit Boards (PCBs). | Feature | Specification | | :--- | :--- | | **Connector Type** | RJ45 (8P8C - 8 Positions, 8 Contacts) | | **Mounting Type** | Through-Hole (THT) | | **Orientation** | Right Angle (90 Degree) | | **Shielding** | Shielded (Metal Shell for EMI/RFI protection) | | **Tab Direction** | Tab-Up | | **LEDs** | Typically contains Integrated LEDs (Green/Yellow) | --- ### 2. Key Electronic Characteristics These parts are engineered to handle high-speed data transmission while maintaining signal integrity. * **Contact Resistance:** Usually rated at 30mΩ to 50mΩ maximum to ensure minimal power loss at the connection point. * **Insulation Resistance:** Typically 500MΩ minimum at 500V DC to prevent leakage between adjacent pins. * **Dielectric Withstanding Voltage:** Often rated for 1000V AC or 1500V DC for 1 minute to ensure safety against voltage spikes. * **Current/Voltage Rating:** Generally rated for 1.5 Amps and 125V AC. --- ### 3. Physical & Material Composition The durability and performance of the connector depend on the materials used in its construction: * **Housing:** High-temperature Thermoplastic (UL 94V-0 rated), suitable for wave soldering processes. * **Contacts:** Phosphor Bronze base with **Gold Plating** (often 6u", 15u", or 30u") over Nickel. Gold prevents corrosion and ensures a reliable electrical path. * **Shield:** Copper Alloy with Nickel or Tin plating to provide a path to ground for electromagnetic interference. --- ### 4. Typical Applications This component is commonly found in the following electronic devices: 1. **Network Switches/Routers:** Providing the physical interface for LAN cables. 2. **Industrial PCs:** Used for robust data communication in factory environments. 3. **Embedded Systems:** Found on development boards (like specialized ARM or FPGA boards) for IoT connectivity. ---
