The **WJFX-U2C1-R** is a specific electronic component, typically categorized as a **USB 2.0 Connector**. Specifically, it is a Type-C female socket designed for Surface Mount Technology (SMT) on Printed Circuit Boards (PCBs). Below is a detailed breakdown of its electronic and mechanical specifications. --- ### 1. Technical Specifications This part is engineered for high-speed data transfer and power delivery in compact electronic devices. | Feature | Specification | | :--- | :--- | | **Interface Type** | USB 2.0 Type-C | | **Gender** | Receptacle (Female) | | **Mounting Type** | SMT (Surface Mount) + Through-hole Shell Legs | | **Number of Pins** | 12-Pin or 24-Pin (Configuration dependent) | | **Current Rating** | 3.0A to 5.0A (for VBUS) | | **Voltage Rating** | 20V DC | | **Operating Temp** | -30°C to +85°C | --- ### 2. Key Electronic Components & Materials The performance of the WJFX-U2C1-R relies on high-quality materials to ensure conductivity and durability: * **Contacts (Pins):** Usually made of **Copper Alloy** with **Gold Plating** over Nickel. Gold plating prevents oxidation and ensures low contact resistance during high-frequency data transmission. * **Insulator:** High-temperature thermoplastic (LCP - Liquid Crystal Polymer) capable of withstanding reflow soldering temperatures (approx. 260°C). * **Shell (Shielding):** Stainless steel or Nickel-plated steel. This acts as an EMI (Electromagnetic Interference) shield and provides structural grounding. --- ### 3. Pinout and Signal Functionality As a USB-C 2.0 part, it does not utilize the SuperSpeed differential pairs found in USB 3.0, focusing instead on the following: 1. **VBUS/GND:** Power supply lines. 2. **D+/D-:** Differential pairs for USB 2.0 data transfer (up to 480 Mbps). 3. **CC1/CC2:** Configuration Channel pins used for cable orientation detection and Power Delivery (PD) negotiations. 4. **SBU1/SBU2:** Sideband Use pins (often used for alternate modes or audio). --- ### 4. Application Use Cases This specific part number is commonly found in: * **Mobile Devices:** Charging ports for smartphones and tablets. * **Peripheral Hardware:** Keyboards, mice, and external hard drive enclosures. * **Power Modules:** DIY USB-C power trigger boards or charging modules. ---
