The **M2PHS2H-AB-R** is a specific part number typically associated with high-performance hardware interfaces, most commonly found in the context of **M.2 (NGFF) to PCIe/SATA adapter cards** or specialized interconnect modules used in industrial computing. Below is a breakdown of the electronic characteristics and technical specifications generally associated with this component. --- ### 1. Technical Specifications Table | Feature | Description | | :--- | :--- | | **Interface Type** | M.2 (Key M or Key B+M) to PCIe x4 / SATA | | **Form Factor** | Low Profile / Standard Height compatible | | **Data Rate** | Up to 32 Gbps (PCIe Gen3 x4) | | **Supported Sizes** | 2230, 2242, 2260, 2280 | | **Operating Voltage** | 3.3V (via PCIe slot) | | **Cooling** | Often includes passive heat sink mounting holes | --- ### 2. Key Electronic Components The "parts" within this assembly usually include several critical sub-components to ensure signal integrity and power stability: * **Voltage Regulators (LDO):** Converts the 12V or 5V power from the motherboard PCIe slot into a stable **3.3V** required by the M.2 SSD. * **Decoupling Capacitors:** Small MLCC (Multi-Layer Ceramic Capacitors) placed near the M.2 connector to filter high-frequency noise and prevent voltage drops during high-speed data bursts. * **Differential Pair Trace Routing:** The PCB (Printed Circuit Board) is designed with controlled impedance (usually 85-100 ohms) to maintain signal integrity for high-speed PCIe lanes. * **Gold Finger Contacts:** The edge connector uses high-micron gold plating to ensure low resistance and durability over multiple insertion cycles. * **LED Indicators:** Often includes a surface-mount LED to indicate "Power Good" status and "Data Activity." --- ### 3.
