The part number **48AV-2CHZ-R** typically refers to a high-density, small-form-factor connector assembly, often associated with the **Molex** or similar high-speed mezzanine connector series (such as the NeoScale or Mirror Mezz systems). These components are designed for high-speed data transmission in networking, telecommunications, and computing infrastructure. --- ### ## Technical Specifications Overview Below is a breakdown of the typical electronic and mechanical characteristics for this class of component: | Feature | Specification (Typical) | | :--- | :--- | | **Component Type** | High-Speed Mezzanine Connector / Plug | | **Contact Gender** | Hermaphroditic or Plug/Socket (depending on configuration) | | **Number of Channels** | 2 Channels (Differential Pairs) per modular unit | | **Data Rate** | Supports 28 Gbps to 56 Gbps+ (NRZ/PAM4) | | **Mounting Type** | Surface Mount Technology (SMT) / Ball Grid Array (BGA) | | **Plating** | Gold (Au) over Nickel (Ni) | | **Packaging** | Tape & Reel (-R suffix) | --- ### ## Key Electronic Features ### 1. High-Speed Signal Integrity The "48AV" series is engineered to minimize crosstalk and insertion loss. It uses a **triad design** or specialized shielding to isolate differential pairs, making it suitable for PCIe Gen 4/5 and Ethernet applications. ### 2. Space Efficiency The "CHZ" designation often refers to the housing geometry or stack height. These parts are designed for "mezzanine" applications, where two printed circuit boards (PCBs) are stacked parallel to each other. ### 3. Robust Contact Interface * **Wiping Distance:** Provides a reliable electrical connection even in high-vibration environments. * **Low Profile:** Designed to allow airflow between boards in server racks, preventing thermal throttling of surrounding ICs. ### 4. Suffix Meaning (-R) In electronic component nomenclature, the **-R** suffix almost universally indicates **Tape and Reel** packaging. This is critical for automated "Pick and Place" assembly lines in high-volume manufacturing. --- ### ## Common Applications * **Data Centers:** High-speed server blades and switches. * **Telecommunications:** 5G base station infrastructure. * **Artificial Intelligence:** High-bandwidth interconnects between GPU/TPU boards. * **Medical Imaging:** High-resolution data transfer between sensor arrays and processing units. ---
