The **M2AS1-5243-R/Q** is a specific part number belonging to a series of high-performance RF (Radio Frequency) connectors, typically associated with high-speed data transmission interfaces like **Mini-SAS HD (High-Density)**. Below is a detailed breakdown of its electronic and mechanical specifications. --- ## 1. Core Specifications The following table highlights the primary technical characteristics of the M2AS1 series: | Feature | Specification | | :--- | :--- | | **Connector Type** | Mini-SAS HD (Internal/External) | | **Impedance** | 100 Ohms (Standard) | | **Data Rate** | Supports up to 12Gb/s per channel (SAS 3.0) | | **Pin Configuration** | Typically 36-position (4-lane) | | **Mounting Type** | Surface Mount (SMT) or Press-fit | | **Plating** | Gold over Nickel (Contact area) | --- ## 2. Component Breakdown The part number can be decoded to understand the specific electronic attributes: ### Mechanical Housing * **Material:** High-temperature LCP (Liquid Crystal Polymer) plastic, designed to withstand reflow soldering temperatures. * **Shielding:** Integrated metal EMI (Electromagnetic Interference) shield to ensure signal integrity at high frequencies. ### Signal Contacts * **Differential Pairs:** The internal pins are arranged in differential pairs to minimize crosstalk and electromagnetic interference. * **Low Insertion Loss:** Engineered to provide a clean signal path for high-speed serialized data. ### Suffix Meanings * **-R:** Generally indicates compliance with **RoHS** (Restriction of Hazardous Substances) standards. * **-Q:** Often refers to specific **Packaging** (e.g., Tape and Reel) or a particular **Quality/Grade** certification for industrial use. --- ## 3. Applications These electronic parts are primarily found in enterprise-level hardware: 1. **Storage Servers:** Connecting RAID controllers to backplanes. 2. **Network Switches:** High-speed data links between boards. 3. **HPC (High-Performance Computing):** Used in clusters where low latency and high bandwidth are critical. 4. **Workstations:** For internal SAS/SATA drive expansion. --- ## 4. Soldering & Assembly Considerations ```markdown * Footprint: Requires precise PCB pad layout for SMT pins. * Coplanarity: Maximum 0.1mm to ensure all leads touch the solder paste. * Pick-and-Place: Usually comes with a vacuum cap for automated assembly. ```
