The **P-RJSSE-5380-01T** is a specific part number from **Amphenol CS (formerly Amphenol ICC)**. It belongs to the RJSSE series of modular jacks, specifically designed for high-speed data transmission and EMI (Electromagnetic Interference) protection. --- ### 1. General Specifications The P-RJSSE-5380-01T is a surface-mount (SMT) modular jack, commonly known as an RJ45 connector, used primarily in networking hardware. | Feature | Specification | | :--- | :--- | | **Connector Type** | RJ45 (8P8C) | | **Series** | RJSSE (High Speed) | | **Mounting Type** | Surface Mount (SMT) | | **Orientation** | Right Angle (Horizontal) | | **Number of Ports** | 1 (Single Port) | | **Shielding** | Shielded with EMI Tabs | | **LED Indicators** | No LEDs (Standard version) | --- ### 2. Key Electronic Features #### A. EMI Suppression (The "S" in RJSSE) This part is specifically engineered for high-performance shielding. It features **EMI tabs** (small metallic springs) on the top and sides of the shield. These tabs ensure a tight, conductive connection between the connector and the device's chassis, effectively grounding the system and reducing noise. #### B. Contact Plating and Conductivity * **Contact Material:** Phosphor Bronze. * **Plating:** Typically features **50 micro-inches of Gold** over Nickel. The high gold content prevents oxidation and ensures low contact resistance over thousands of mating cycles. * **Data Rate:** Designed to support Category 5e (Cat5e) and Category 6 (Cat6) performance levels, suitable for 10/100/1000 Mbps Ethernet. #### C. Physical Construction * **Housing:** High-temperature thermoplastic (UL 94V-0 rated), which is necessary for reflow soldering processes used in SMT assembly. * **Shielding:** Copper alloy with tin plating. --- ### 3. Dimensional Data (Approximate) | Dimension | Value | | :--- | :--- | | **Height** | ~13.00 mm | | **Width** | ~15.50 mm | | **Depth** | ~19.00 mm | --- ### 4. Common Applications Due to its robust shielding and SMT design, this part is frequently found in: * **Networking Hubs and Switches:** Where space is limited and high-speed data integrity is critical. * **Industrial Servers:** Requiring reliable grounding to prevent data loss. * **Consumer Electronics:** High-end routers or laptops where a low-profile SMT connector is preferred over through-hole. ---
