The part number **48AV-2YV6-R** refers to a high-performance **Micro-SDXC memory card**, typically produced by manufacturers like **Lexar** or industrial storage providers. It is designed for high-speed data logging, 4K video recording, and mobile applications. --- ### Technical Specifications | Feature | Specification | | :--- | :--- | | **Storage Capacity** | 128GB to 256GB (Varies by sub-series) | | **Interface** | UHS-I (Ultra High Speed Phase I) | | **Speed Class** | Class 10, U3, V30 | | **Application Class** | A2 (Optimized for App performance) | | **Read Speed** | Up to 160 MB/s | | **Write Speed** | Up to 70-120 MB/s | | **Form Factor** | MicroSDXC | --- ### Key Component Features #### 1. Performance Standards * **V30 (Video Speed Class):** Guarantees a minimum sustained write speed of 30MB/s, making it suitable for 4K UHD video without dropped frames. * **A2 Rating:** This is critical for mobile devices. It indicates high **IOPS** (Input/Output Operations Per Second), allowing Android apps to run directly from the card with minimal latency. #### 2. Durability & Protection The "R" suffix often denotes a "Rugged" or "Retail" version, featuring: * **Waterproof:** Protection against submersion. * **Shockproof:** Resistance to physical vibration and drops. * **X-Ray Proof:** Safe for airport security scanners. * **Temperature Proof:** Operational range typically between -25°C to 85°C. #### 3. Controller & NAND Flash Inside the casing, this part consists of: * **NAND Flash:** Usually 3D TLC (Triple-Level Cell) for a balance between density and cost. * **Flash Controller:** Manages wear-leveling (ensuring even usage of memory cells) and ECC (Error Correction Code) to prevent data corruption. --- ### Typical Applications * **Action Cameras:** GoPro and DJI drones requiring high bitrate 4K recording. * **Smartphones:** Expanding internal storage for high-end Android devices. * **Gaming Consoles:** Used extensively for the Nintendo Switch to reduce load times. * **Industrial IoT:** Edge computing devices that require reliable, high-speed logging.
