The **W2PE-51B-R2** is a specialized electronic component, typically identified as a **high-density, micro-pitch connector** (often associated with high-speed interface applications like Thunderbolt, DisplayPort, or proprietary docking connections). Below is a breakdown of its technical characteristics and electronic composition. --- ### 1. General Specifications This part belongs to the category of high-performance interconnects designed for compact electronic devices. | Feature | Specification | |:---|:---| | **Pin Count** | 51 Pins | | **Pitch** | Ultra-fine (typically 0.4mm or 0.5mm) | | **Mounting Type** | Surface Mount Technology (SMT) | | **Orientation** | Right-Angle or Vertical (depending on specific R2 revision) | | **Contact Material** | Copper Alloy with Gold Plating | | **Body Material** | High-Temperature Thermoplastic (LCP) | ### 2. Key Electronic Characteristics The W2PE series is engineered to handle specific electrical requirements for modern high-speed data transmission: * **Contact Resistance:** Engineered to be extremely low (typically < 50 mΩ) to minimize signal loss and heat generation. * **Current Rating:** Despite the small size, these pins are usually rated for 0.5A per contact. * **Dielectric Withstanding Voltage:** Designed to withstand ~250V AC/minute to prevent arcing between the closely spaced pins. * **Impedance Control:** The geometry of the pins and the plastic housing are optimized to maintain a specific differential impedance (often 85Ω or 100Ω) for high-speed protocols. ### 3. Structural Components The "R2" suffix often denotes a revision or specific packaging/mechanical reinforcement: 1. **Shielding Shell:** Often features a metal "can" or shell to provide EMI (Electromagnetic Interference) protection and mechanical grounding. 2. **Solder Tabs:** Large metal tabs on the sides of the connector provide mechanical stability to the PCB, preventing the SMT pins from shearing off during cable insertion/removal. 3. **Gold Plating:** Critical for preventing oxidation on the 51 micro-pins, ensuring long-term conductivity in high-cycle environments. ### 4. Typical Applications * **Mobile Computing:** Internal connections between a motherboard and a high-resolution display panel (eDP). * **Docking Stations:** High-bandwidth interfaces for transmitting video, data, and power simultaneously. * **Medical Devices:** Compact imaging equipment requiring high-density signal routing. ---
