The part number **M2RTS-R-21-M2SLASHQ** refers to a high-performance **M.2 (NGFF) connector**, typically used in industrial and consumer computing applications to interface between a motherboard and an SSD or wireless module. --- ## 1. Technical Specifications This connector is designed for high-speed data transmission and durability. Below are the primary electronic and mechanical specifications: | Feature | Specification | | :--- | :--- | | **Interface Type** | M.2 (Next Generation Form Factor) | | **Pitch** | 0.5 mm | | **Mounting Type** | Surface Mount Technology (SMT) | | **Height** | 2.1 mm (Standard low profile) | | **Number of Pins** | 67-75 Positions (Application dependent) | | **Contact Material** | Copper Alloy with Gold Plating | | **Operating Voltage** | 50V AC/DC | | **Current Rating** | 0.5A per pin | --- ## 2. Key Decoding (Part Number Breakdown) While specific to certain manufacturers (such as LOTES or similar Tier-1 vendors), the code usually breaks down as follows: 1. **M2RTS**: Series designation for M.2 Right-Angle Top Mount. 2. **R**: Right-angle orientation. 3. **21**: Refers to the **2.1mm stack height**, which determines how high the M.2 card sits above the PCB. 4. **M2**: Refers to "M-Key" or "B-Key" slotting (usually M-Key for NVMe SSDs). 5. **SLASHQ**: Specific manufacturing revision, plating thickness, or packaging (Tape & Reel) indicator. --- ## 3. Electronic Characteristics ### Signal Integrity * **High-Speed Data**: Supports PCIe Gen 3, Gen 4, and SATA 3.0 protocols. * **Impedance Control**: Designed for 100-ohm differential impedance to minimize signal reflection. * **EMI Shielding**: The metal shell/tabs provide grounding points to reduce electromagnetic interference. ### Durability * **Mating Cycles**: Typically rated for 60 to 100 insertion/extraction cycles. * **Insulation Resistance**: Minimum 500MΩ to prevent leakage between dense pin configurations. --- ## 4. Typical Applications This specific 2.1mm height connector is commonly found in: * **Industrial PCs**: Where vibration resistance is required. * **Laptops/Ultrabooks**: To maintain a slim chassis profile. * **SBCs (Single Board Computers)**: For adding NVMe storage or AI acceleration modules.
