The **M2PHS2H-C3-R/Q** is a specific part number typically associated with **M.2 (NGFF) high-performance connectors**. These components are critical in modern computing for interfacing SSDs, Wi-Fi modules, and LTE cards with motherboards. --- ### 1. Technical Specifications Breakdown The part number usually encodes specific physical and electrical characteristics. Below is a breakdown of what these codes typically represent in the context of M.2 connectors: | Feature | Specification | Description | | :--- | :--- | :--- | | **Connector Type** | M.2 (NGFF) | Next Generation Form Factor. | | **Pitch** | 0.50 mm | The distance between the center of one contact and the next. | | **Height (H)** | 3.2mm - 4.2mm | Refers to the "stack height" (distance from PCB to the module). | | **Keying** | B, M, or B+M | Determines the notch position to prevent incorrect insertion. | | **Mounting** | SMT (Surface Mount) | Soldered directly onto the surface of the PCB. | | **Plating** | Gold (Au) | High-quality plating to prevent oxidation and ensure signal integrity. | --- ### 2. Key Electronic Characteristics High-speed connectors like the M2PHS2H series are engineered for data integrity. Their electronic design focuses on: * **Signal Integrity:** Optimized for PCIe Gen 3/Gen 4 speeds, ensuring minimal crosstalk and electromagnetic interference (EMI). * **Contact Resistance:** Typically rated at **55mΩ Max**, ensuring minimal power loss across the connection. * **Current Rating:** Usually **0.5A per pin**, sufficient for high-power NVMe SSDs. * **Voltage Rating:** Standard **50V AC/DC**. * **Durability:** Rated for approximately **60 mating cycles**, as M.2 devices are not intended for frequent "hot-swapping." --- ### 3. Usage Context This part is commonly found in: 1. **Industrial PCs:** Due to the "R/Q" suffix which often denotes ruggedized or high-retention variations. 2. **Laptops/Ultrabooks:** Where vertical space (Z-height) is extremely limited. 3. **IoT Gateways:** Used for connecting cellular modems or AI acceleration modules. --- ### 4. Comparison Table: Standard vs. Ruggedized M.2 | Feature | Standard M.2 | M2PHS2H Series (High Spec) | | :--- | :--- | :--- | | **Vibration Resistance** | Standard | Enhanced (Locking mechanisms) | | **Operating Temp** | -40°C to +85°C | -40°C to +105°C (often) | | **Data Rate** | Up to PCIe 3.0 | Optimized for PCIe 4.0/5.0 |
