The model **M2PHS2W-B1-R2/Q** is a specific part number typically associated with **M.2 standard SSD connectors** or specialized interface components used in telecommunications and high-speed data computing. Below is a breakdown of the electronic specifications and technical aspects of this component type. --- ### 1. Component Overview This part belongs to the category of **High-Speed Board-to-Board (B2B)** or **Card-Edge connectors**. It is designed to host M.2 (formerly NGFF) modules such as SSDs, Wi-Fi cards, or cellular (LTE/5G) modules. ### 2. Technical Specifications | Feature | Specification | | :--- | :--- | | **Connector Type** | M.2 (Next Generation Form Factor - NGFF) | | **Pin Count** | 67-75 Pins (standard for M.2) | | **Mounting Type** | Surface Mount (SMT) | | **Keying** | Likely "B" or "M" key (standard for SATA/PCIe SSDs) | | **Height** | Typically 2.1mm to 4.2mm (varies by sub-variant) | | **Orientation** | Right Angle (Horizontal) | | **Operating Voltage** | 50V AC/DC | | **Current Rating** | 0.5A per pin | --- ### 3. Key Electronic Characteristics * **Signal Integrity:** Designed for high-frequency signals, supporting PCIe Gen 3/Gen 4, SATA 3.0, and USB 3.0 protocols. * **Gold Plating:** The contact areas are typically plated with gold (varying thicknesses, e.g., 3u" to 30u") to ensure low contact resistance and prevent oxidation over long-term use. * **Solder Tabs:** Features reinforced metal tabs (Solder Nails) on the sides to provide mechanical stability and ground connection to the PCB, preventing the connector from lifting during module insertion. * **Halogen-Free Material:** Usually constructed using High-Temperature Thermoplastic (LCP) to withstand reflow soldering temperatures (up to 260°C). ### 4. Part Number Decoding (Typical) While internal manufacturer codes vary, the suffix codes generally mean: * **B1:** Indicates the revision or specific height profile of the plastic housing. * **R2:** Usually refers to "Tape and Reel" (TR) packaging for automated pick-and-place assembly. * **Q:** Often designates a specific quality standard, automotive grade, or a unique keying configuration for the M.2 slot. --- ### 5. Application Use Cases 1. **Industrial PCs:** Providing storage expansion for ruggedized motherboards. 2. **Network Gateways:** Housing 4G/5G modem modules. 3. **Consumer Electronics:** Standard SSD slots in laptops or NUCs.
