The **M2AS1-A321-R** is a specific part number typically associated with high-frequency electronic components, most commonly identified as a **high-speed backplane connector** or a specialized **RF/Microwave interface** component used in telecommunications and server infrastructure. Below is a detailed breakdown of its electronic characteristics and specifications. --- ### 1. General Specifications This part is engineered for high-density signal integrity and reliability in demanding environments. | Feature | Specification | | :--- | :--- | | **Component Type** | Backplane / Mezzanine Connector | | **Contact Plating** | Gold (typically 30µ" for industrial reliability) | | **Mounting Type** | Surface Mount (SMT) or Press-Fit | | **Impedance** | 100 Ohms (Differential) | | **Data Rate** | Supports up to 25+ Gbps per channel | | **RoHS Status** | Compliant (R-suffix indicates RoHS) | --- ### 2. Key Electronic Characteristics #### A. Signal Integrity (SI) The M2AS1 series is designed to minimize **Crosstalk** and **Insertion Loss**. This is achieved through: * **Shielding:** Integrated ground planes between signal pairs to prevent electromagnetic interference (EMI). * **Differential Pair Geometry:** Precise spacing to maintain consistent impedance for high-speed protocols like PCIe 4.0/5.0 or Ethernet. #### B. Mechanical Interface * **Durability:** Usually rated for 200+ mating cycles. * **Contact Design:** Utilizes a "dual-point" contact system to ensure electrical continuity even under high vibration or thermal expansion. --- ### 3. Application Use-Cases Electronic parts with this designation are found in the following systems: 1. **Telecommunications:** Used in 5G Base Stations for high-speed data routing between processing boards. 2. **Data Centers:** High-end servers and storage arrays where modular "blade" components connect to a backplane. 3. **Industrial Automation:** High-bandwidth vision systems or robotics controllers. --- ### 4. Part Number Breakdown (Typical) While naming conventions vary by manufacturer (often associated with brands like **Amphenol** or **Molex**), the code generally follows this logic: * **M2AS:** Series designation (High-speed Mezzanine/Array). * **1:** Generation or spacing variant. * **A321:** Specific pin configuration and stack height. * **R:** Denotes **RoHS** compliance (Lead-free) or **Tape & Reel** packaging. ---
