The **WJFX-U3EB-R/Q** is a high-performance, industry-standard **USB 3.0 (USB 3.1 Gen 1) Connector**. These components are typically manufactured by specialized interconnect hardware firms and are designed for high-speed data transmission and durable physical connections in consumer electronics and industrial equipment. ### 1. Technical Specifications | Feature | Specification | | :--- | :--- | | **Connector Type** | USB 3.0 Type-A (Standard) | | **Interface Speed** | Up to 5 Gbps (SuperSpeed) | | **Mounting Type** | Through-Hole (THT) / Right Angle | | **Orientation** | Horizontal | | **Contact Material** | Copper Alloy (typically Gold plated) | | **Voltage Rating** | 30V AC/DC | | **Current Rating** | 1.8A (Power pins), 0.25A (Signal pins) | | **Durability** | ~5,000 Mating Cycles | --- ### 2. Key Design Components #### A. Physical Construction * **Housing:** Usually made of High-Temperature Thermoplastic (UL94V-0 rated), allowing it to withstand wave soldering processes. * **Shielding:** A metal outer shell (Stainless steel or Nickel-plated brass) provides EMI/RFI protection and ensures a common ground connection. * **Retention:** Often features "Kinked" leads or "Board Locks" to hold the connector securely to the PCB during the soldering process. #### B. Pin Configuration The USB 3.0 architecture requires **9 pins**: 1. **4 Pins (Legacy):** Compatible with USB 2.0 (VCC, D-, D+, GND). 2. **5 Pins (SuperSpeed):** Added for high-speed differential pairs (TX+, TX-, RX+, RX-, and a dedicated GND drain). --- ### 3. Suffix Breakdown (R/Q) In electronic part numbering, the suffixes usually denote packaging or minor variations: * **-R:** Generally stands for **Tape & Reel** packaging (for automated pick-and-place assembly) or **RoHS Compliant**. * **-Q:** Often refers to **Quality/Automotive** grading or a specific manufacturer's production batch code. --- ### 4. Application Areas * **Computing:** Motherboards, Laptops, and Docking Stations. * **Peripherals:** External Hard Drives (HDDs), SSD enclosures, and Flash drives. * **Industrial:** High-speed machine vision cameras and data loggers. * **Embedded Systems:** Single-board computers (like Raspberry Pi or Jetson modules). --- ### 5. Footprint Example (Generic) ```c // PCB Layout Consideration // Pins 1-4 are positioned at the front // Pins 5-9 are positioned in a row behind them // Shell tabs require large plated through-holes for mechanical strength ```
