The part number **10VF2-4W40-R** typically refers to a high-density, miniature **Board-to-Board connector** or a specific **FFC/FPC (Flat Flexible Cable) connector**, often utilized in compact consumer electronics like smartphones, tablets, or medical devices. Below is a breakdown of its technical specifications and characteristics. --- ### 1. General Specifications Based on the industry standard nomenclature for these types of connectors: | Feature | Specification | | :--- | :--- | | **Component Type** | FPC/FFC Connector or Board-to-Board | | **Pitch** | 0.4 mm (Common for '40' series) | | **Number of Pins** | 10 Pins (Indicated by '10') | | **Mounting Type** | Surface Mount Technology (SMT) | | **Orientation** | Vertical or Right Angle (Depending on exact series) | | **RoHS Status** | Compliant (Indicated by '-R') | --- ### 2. Key Technical Attributes #### A. Miniaturization The "0.4mm pitch" implies that the center of one contact pin is only 0.4mm away from the next. This allows for a very high density of signals in a tiny footprint, which is essential for modern mobile hardware. #### B. Mechanical Robustness * **Mating Cycles:** Usually rated for 20 to 50 cycles (not intended for frequent plugging/unplugging). * **Locking Mechanism:** Often features a "Flip-lock" or "Slider" actuator to ensure the flexible cable stays securely in place. #### C. Electrical Ratings * **Current Rating:** Typically 0.2A to 0.5A per pin. * **Voltage Rating:** Usually around 50V AC/DC. * **Contact Resistance:** Low resistance (usually < 50mΩ) to maintain signal integrity. --- ### 3. Applications These parts are found in environments where space is at a premium: * **Mobile Devices:** Connecting LCD screens, camera modules, or battery management systems to the main PCB. * **Wearables:** Smartwatches and fitness trackers. * **Automotive:** Interior displays and sensor arrays. --- ### 4. Part Number Breakdown (Typical) | Segment | Meaning | | :--- | :--- | | **10** | Number of positions/contacts. | | **VF2** | Series designation (often refers to Vertical or specialized height). | | **4W** | Often refers to the width or specialized contact type. | | **40** | Pitch code (40 = 0.4mm). | | **R** | Packaging/Environmental (Tape & Reel or RoHS compliant). |
