The **MXAP-S3F-R3** is a specialized electronic component, typically categorized as a **High-Density Board-to-Board (BtB) Connector**. These parts are designed for high-performance signal integrity in compact electronic assemblies. ### 1. Technical Specifications The MXAP series is engineered for high-speed data transmission and durability in harsh environments. | Feature | Specification (Typical) | | :--- | :--- | | **Component Type** | Board-to-Board Plug/Receptacle | | **Pitch** | 0.5mm to 0.8mm (varies by sub-series) | | **Number of Rows** | Dual Row | | **Mounting Type** | Surface Mount (SMT) | | **Contact Material** | Copper Alloy with Gold Plating | | **Data Rate Support** | High-speed (PCIe Gen 3/4 compatible) | --- ### 2. Key Electronic Characteristics The "S3F-R3" designation refers to specific mechanical and electrical configurations: * **Shielding (S3):** This often denotes a specific shielding configuration to prevent Electromagnetic Interference (EMI) and Cross-talk between high-speed signal lines. * **Flash Gold Plating (F):** The contacts are usually treated with gold flash over nickel to ensure low contact resistance and prevent oxidation over long periods. * **Tape and Reel Packaging (R3):** The "R3" suffix typically refers to the packaging style for automated pick-and-place assembly machines (Reel size/quantity). --- ### 3. Structural Breakdown | Part Section | Function | | :--- | :--- | | **Insulator Body** | High-temperature thermoplastic (LCP) capable of withstanding reflow soldering temperatures. | | **Retention Solder Tabs** | Metal tabs on the sides that provide mechanical strength to prevent the connector from being ripped off the PCB during unmating. | | **Signal Pins** | Precisely shaped pins designed for low insertion force (LIF) and high mating cycles. | --- ### 4. Common Applications Due to its high density and signal integrity, this part is commonly found in: 1. **Industrial Computing:** Connecting carrier boards to COM (Computer-on-Module) units. 2. **Medical Equipment:** High-resolution imaging sensors. 3. **Automotive Electronics:** Infotainment systems and ADAS sensor modules. 4. **Telecommunications:** Network switches and high-speed routers.
