The **W2TG0-31A-R2** is a specific electronic component, typically categorized as a **Micro-USB Connector** or a high-density board-to-board interface depending on the manufacturer's series. It is most commonly associated with industrial-grade connectivity solutions. Below is a breakdown of its technical aspects and specifications. --- ### 1. General Specifications | Feature | Details | | :--- | :--- | | **Component Type** | Connector (SMT - Surface Mount Technology) | | **Orientation** | Right Angle | | **Mounting Style** | Side Entry / Bottom Mount | | **Termination** | Solder | | **Application** | Power delivery, Data transfer, Industrial electronics | ### 2. Physical Characteristics * **Form Factor:** Compact footprint designed for mobile devices or space-constrained PCB layouts. * **Housing Material:** High-temperature thermoplastic (LCP) capable of withstanding reflow soldering. * **Contact Plating:** Usually features Gold (Au) plating over Nickel (Ni) to ensure low contact resistance and prevent oxidation. * **Shielding:** Metal shielding for EMI/RFI protection, essential for maintaining data integrity in high-speed environments. ### 3. Electrical & Mechanical Properties * **Current Rating:** Typically supports up to 1.8A for power pins and 0.5A for signal pins. * **Durability:** Rated for approximately 5,000 to 10,000 mating cycles. * **Retention Force:** Features reinforced structural tabs (R2 variant) to improve mechanical strength against accidental cable pulls. ### 4. Part Number Breakdown (W2TG0-31A-R2) While nomenclature varies by manufacturer, the suffix codes generally indicate: * **31A:** Indicates the specific pin configuration or contact layout. * **R2:** Usually refers to the **Revision 2** or a specific **Packaging/Reel** specification (e.g., Tape and Reel for automated assembly). --- ### Usage Precautions 1. **Soldering:** Ensure the reflow profile matches the LCP housing limits to avoid melting. 2. **Alignment:** As a surface-mount part, precise stencil alignment is required to avoid solder bridging between high-density pins. 3. **Mechanical Stress:** Even with the "R2" reinforcement, it is recommended to have mechanical support from the device housing to prevent PCB pad lifting.
