The **M2PHS2H-C3-R2/Q** is a high-density, high-performance connector typically utilized in industrial, telecommunications, or high-speed computing environments. It belongs to a class of modular, multi-pin interconnects designed for board-to-board or cable-to-board applications. --- ### 1. General Specifications While specific datasheets are often proprietary to manufacturers like **Molex** or **Samtec** (depending on the exact series prefix), the nomenclature generally follows this breakdown: | Component Attribute | Description | | :--- | :--- | | **Series Type** | High-speed, high-density mezzanine or backplane connector. | | **Pitch** | Typically small (0.5mm, 0.8mm, or 1.27mm) to save PCB real estate. | | **Configuration** | Male (Plug) or Female (Socket) depending on the 'P' or 'S' designation. | | **Pin Count** | High density (multi-row layout). | | **Plating** | Gold (Au) flash or selective gold over nickel to prevent oxidation. | --- ### 2. Key Electronic Features These connectors are engineered for signal integrity and durability under electrical stress. * **Impedance Control:** Designed to maintain 50Ω (single-ended) or 100Ω (differential) impedance for high-speed data transmission (e.g., PCIe Gen 4/5, Ethernet). * **Contact Resistance:** Extremely low (typically < 30mΩ) to minimize heat dissipation and voltage drop. * **Current Rating:** Usually ranges from 0.5A to 1.5A per pin, though some pins may be grouped for power delivery. * **EMI/EMC Shielding:** The "Q" or "R" suffixes often denote specific shielding properties or orientation (Right-angle vs. Straight) to mitigate electromagnetic interference. --- ### 3. Application Use Cases Due to the robust nature of the **M2PHS2H** series, it is found in: 1. **FPGA Development Boards:** Connecting core modules to daughterboards. 2. **Network Switches:** High-bandwidth data routing between line cards. 3. **Medical Imaging:** Reliable signal transfer for high-resolution sensors. 4. **Embedded Systems:** Stacked PCB configurations where vertical space is limited. --- ### 4. Technical Pin-out Orientation | Designator | Meaning | | :--- | :--- | | **-C3** | Often refers to the contact style or specific height (stacking height). | | **-R2** | Indicates the Revision level or Packaging (e.g., Tape & Reel). | | **-Q** | Usually signifies Automotive grade or a specific Quality testing standard. | ---
