The part number **F2VF-C4-R** typically refers to a high-speed, high-density mezzanine connector system, often associated with the **Samtec SEARAY™ (SEAM/SEAF Series)** family or similar high-speed board-to-board interconnects used in telecommunications and data networking. --- ### 1. General Specifications These components are designed for high-signal integrity and high-density applications. | Feature | Specification (Typical) | | :--- | :--- | | **Component Type** | High-Speed Mezzanine Connector | | **Pitch** | 1.27 mm (0.050") | | **Data Rate** | Up to 28+ Gbps | | **Mounting Type** | Surface Mount (SMT) | | **Termination** | Solder Charge / BGA (Ball Grid Array) | | **Orientation** | Vertical | --- ### 2. Key Electronic Characteristics * **Signal Integrity:** Optimized for differential pair routing. The internal grounding structure minimizes crosstalk and maintains impedance consistency. * **High Density:** Features a grid-array layout (multiple rows and columns), allowing hundreds of I/Os in a very small PCB footprint. * **Durability:** Gold-plated contacts ensure low contact resistance and high mating cycles (typically 100+ cycles). * **Low Profile:** Available in various stack heights (ranging from 7mm to 40mm) to accommodate different PCB spacing requirements. --- ### 3. Common Applications Due to its high bandwidth capabilities, this part is found in: 1. **Network Switches & Routers:** Connecting daughter cards to backplanes. 2. **FPGA Development Boards:** Used as high-speed expansion headers (e.g., FMC - FPGA Mezzanine Card standards). 3. **Medical Imaging:** High-speed data transfer between sensors and processing units. 4. **Servers:** High-performance computing (HPC) environments. --- ### 4. Technical Breakdown of Suffixes In the context of these electronic parts: * **"C4":** Often refers to the contact plating or the specific row configuration (e.g., 4 rows of pins). * **"-R":** Frequently denotes **Tape and Reel** packaging, indicating the part is intended for automated pick-and-place assembly lines. ---
