The part number **10007290-R0850CELF** refers to a high-speed, high-density connector, typically part of the **AirMax VS/VS2** series manufactured by **Amphenol ICC (formerly FCI)**. These components are primarily used in telecommunications and data networking equipment, such as blade servers and routers, to connect a backplane to a daughtercard. --- ### Technical Specifications | Feature | Specification | | :--- | :--- | | **Manufacturer** | Amphenol Communications Solutions (FCI) | | **Series** | AirMax VS (Vertical Shieldless) | | **Connector Type** | Header / Plug (Right Angle) | | **Number of Positions** | 120 (approx. based on 5-pair, 8-column config) | | **Pitch** | 2.00mm | | **Mounting Type** | Through Hole - Press-Fit (Eye-of-the-needle) | | **Data Rate** | Up to 12.5 Gb/s (depending on system design) | | **Compliance** | RoHS Compliant (indicated by "LF" suffix) | --- ### Key Characteristics 1. **AirMax VS Technology**: This design uses an "air-dielectric" between conductors. By eliminating the need for heavy metal shields between differential pairs, the connector reduces weight, cost, and improves airflow within the chassis. 2. **Press-Fit Termination**: The "CELF" suffix often denotes a specific lead-free finish and a compliant-pin (press-fit) attachment method. This allows for assembly to the PCB without soldering, making repairs easier and reducing thermal stress on the board. 3. **Scalability**: The R0850 designation typically refers to the physical configuration (number of columns and rows). In this case, it is a 5-pair configuration, allowing for high-density signal routing. 4. **Signal Integrity**: Despite being shieldless, the geometry of the pins is optimized to minimize crosstalk and maintain impedance control for high-speed differential signaling. --- ### Common Applications * **Networking**: Core routers and high-end switches. * **Storage**: Storage Area Network (SAN) equipment. * **Computing**: Servers and high-performance computing (HPC) clusters. * **Industrial**: High-end medical imaging or industrial automation controllers.
