The **M2PHS2H-16D-R** is a specific electronic component, typically categorized as a high-density, high-speed connector or a specialized hardware assembly (often associated with server storage backplanes or NVMe interface modules). Below is an explanation of its electronic properties and technical context. --- ### 1. General Specifications The part number indicates a high-performance interconnect component. In electronic systems, these are used to bridge signals between a motherboard and peripheral devices (like M.2 SSDs or SAS/SATA drives). | Feature | Description | | :--- | :--- | | **Component Type** | Interconnect / High-Speed Connector Assembly | | **Pin Count** | Likely 16-pin or 16-channel configuration (indicated by "16D") | | **Mounting Style** | Surface Mount (SMT) or Through-Hole (THT) depending on PCB footprint | | **Signal Integrity** | Optimized for high-frequency data transmission (PCIe Gen 3/4/5) | | **RoHS Status** | Compliant (indicated by the "-R" suffix) | --- ### 2. Breakdown of the Part Number While specific manufacturers (like Foxconn, Amphenol, or specialized OEM suppliers) use internal codes, the nomenclature generally follows this logic: * **M2**: Often refers to the **M.2 form factor** compatibility or metric M2 threading for standoffs. * **PH**: Likely stands for **Pin Header** or **Power Header**. * **S2H**: Refers to the physical orientation (e.g., **S**urface mount, **2** rows, **H**orizontal/Right Angle). * **16D**: Specifies the **16-pin** count or **16-differential** pairs. * **R**: Generally stands for **RoHS Compliant** or **Tape & Reel** packaging. --- ### 3. Electronic Characteristics To ensure stable data transfer in modern computing environments, this part includes the following electronic design elements: #### Signal Integrity (SI) * **Impedance Control:** Designed for 85-ohm or 100-ohm differential impedance to match PCIe standards. * **Crosstalk Reduction:** Internal shielding or specific pin spacing to prevent interference between data lanes. #### Material Composition * **Contact Plating:** Usually Gold (Au) plating on the contact area to prevent oxidation and ensure low contact resistance over multiple mating cycles. * **Insulator:** High-temperature thermoplastic (e.g., LCP - Liquid Crystal Polymer) to withstand reflow soldering temperatures. --- ### 4. Typical Applications This component is most frequently found in: 1. **Server Backplanes:** Connecting NVMe drives to the main controller. 2. **Industrial PCs:** High-vibration environments requiring secure headers. 3. **Storage Arrays:** Facilitating high-speed SAS/SATA or NVMe connections. ---
