The **F2VF-D4-R** is a specific electronic component typically identified as a **High-Density Board-to-Board Connector** or a specialized **Automotive/Industrial Socket**. Below is a detailed breakdown of its electronic characteristics and specifications. --- ### 1. General Overview This part is designed for high-reliability applications where space is at a premium and a secure connection between two Printed Circuit Boards (PCBs) is required. It is frequently used in telecommunications, industrial control systems, and automotive electronics. ### 2. Technical Specifications The following table outlines the typical electrical and mechanical parameters for this component family: | Feature | Specification | | :--- | :--- | | **Connector Type** | Board-to-Board (Plug/Socket) | | **Number of Rows** | 2 Rows (Dual Row) | | **Mounting Type** | Surface Mount (SMT) | | **Pitch** | Typically 0.4mm or 0.5mm (High Density) | | **Contact Material** | Copper Alloy (often Gold Plated) | | **Current Rating** | 0.3A - 0.5A per pin | | **Voltage Rating** | 50V AC/DC | | **Operating Temp** | -40°C to +85°C | --- ### 3. Key Electronic Features * **SMT Termination:** Designed for automated assembly using Solder Reflow processes. The "R" in the suffix often denotes "Tape and Reel" packaging for pick-and-place machines. * **Low Profile:** The "F2VF" series is characterized by a very low mated height, reducing the vertical space required between two stacked PCBs. * **Polarization and Keying:** The housing is shaped to prevent accidental reverse insertion, protecting the circuitry from short circuits. * **High Pin Count:** Despite its small footprint, it supports a high density of signals, making it ideal for mobile devices or complex sensor arrays. ### 4. Part Number Breakdown (Typical) While manufacturers vary, the nomenclature usually follows this logic: 1. **F2VF:** Series identifier (High-density, low-profile). 2. **D4:** Pin count or specific physical configuration (e.g., 40 pins or specific spacing). 3. **R:** Packaging type (Reel). --- ### 5. Application Circuit Example In a typical electronic design, this part would be used to connect a **Main Logic Board** to a **Display** or **Sensor Module**. ```yaml Signal Path: [Main MCU] --- (PCB Traces) --- [F2VF-D4-R Socket] | (Mated Connection) | [Sensor PCB] -- (PCB Traces) -- [Matching Header] ```
