The part number **M2XF2-S2V1-R** typically refers to a specific configuration of a high-performance **M.2 (NGFF) connector**, often manufactured by companies like *Lotes* or other high-end interconnect suppliers. These components are critical in modern computing for interfacing SSDs, Wi-Fi modules, and AI accelerators. --- ### 1. Technical Specifications Breakdown The alphanumeric code describes the physical and electrical characteristics of the connector. Here is a general breakdown of the electronic parts involved: | Feature | Specification | Description | | :--- | :--- | :--- | | **Form Factor** | M.2 (NGFF) | Next Generation Form Factor for slim devices. | | **Pin Count** | 67 / 75 Pins | Standard M.2 pin density for high-speed data. | | **Keying** | M-Key or B-Key | Defines the interface (e.g., PCIe x4 vs SATA/USB). | | **Mounting Type** | SMT (Surface Mount) | Soldered directly to the PCB surface. | | **Orientation** | Right Angle / Top Mount | Horizontal insertion parallel to the motherboard. | | **Plating** | Gold (Au) | High conductivity and oxidation resistance on contacts. | --- ### 2. Key Electronic Components & Design The M2XF2 series is engineered to handle high-frequency signals. The electronic design focuses on three main areas: #### A. Signal Integrity (High-Speed Lanes) The internal copper alloy contacts are designed to support **PCIe Gen 4 or Gen 5** speeds. This requires: * **Low Crosstalk:** Spatial separation between differential pairs. * **Impedance Control:** Maintaining 85-100 ohms to prevent signal reflection. #### B. Housing Material (Thermoplastic) The "body" of the connector is usually made of **LCP (Liquid Crystal Polymer)**. * **Heat Resistance:** Withstands reflow soldering temperatures (up to 260°C). * **Halogen-Free:** Meets environmental safety standards (RoHS/Reach). #### C. Solder Nails/Tabs The "R" in the suffix often denotes **Reel packaging** for automated assembly, but physically, the part includes reinforced metal tabs (solder nails) on the sides. These provide: * **Mechanical Grounding:** Reducing EMI (Electromagnetic Interference). * **Strain Relief:** Preventing the connector from ripping off the PCB during SSD insertion. --- ### 3. Application Use-Cases This specific connector type is integrated into various electronic assemblies: 1. **Motherboards:** For NVMe SSD expansion slots. 2. **Industrial PCs:** Compact storage solutions in rugged environments. 3. **Edge AI Modules:** Interfacing with M.2 format NPU (Neural Processing Unit) cards. ---
