The part number **47LPQ-A2BG-R** refers to a high-performance **Magnetic RJ45 Connector** (Integrated Connector Module or ICM) manufactured by **Abracon** (specifically under their LAN-Line series). These components are essential in networking hardware, combining a standard RJ45 jack with the necessary isolation transformers and filters required for Ethernet communication. --- ## 1. Technical Specifications | Feature | Specification | | :--- | :--- | | **Component Type** | RJ45 Integrated Connector Module (ICM) | | **Ethernet Speed** | 10/100/1000 Base-T (Gigabit Ethernet) | | **Number of Ports** | 1 Port (Single) | | **Tab Direction** | Tab-Down | | **Mounting Type** | Through-Hole (THT) | | **LED Configuration** | Green (Left) / Yellow (Right) | | **Shielding** | EMI Finger Shielded | | **Operating Temp** | -40°C to +85°C (Industrial Grade) | --- ## 2. Key Electronic Functions ### A. Magnetic Isolation The "47LPQ" series contains internal 1:1 isolation transformers. These serve three critical purposes: 1. **DC Isolation:** Prevents direct current from damaging sensitive PHY (Physical Layer) chips. 2. **Common Mode Rejection:** Filters out electromagnetic interference (EMI) coming from the Ethernet cable. 3. **Impedance Matching:** Ensures the 100-ohm differential impedance of the twisted-pair cable matches the circuit board requirements. ### B. Integrated LEDs The **A2BG** suffix indicates the LED configuration. In this specific model: * **A2:** Designates the internal circuit schematic. * **B:** Green LED. * **G:** Yellow/Gold LED. These LEDs are driven by the Ethernet controller to indicate link status and data activity. ### C. Shielding and Grounding The outer metal shell provides a Faraday cage effect, protecting the signal from external noise and reducing the emissions from the device itself to comply with FCC/CE regulations. --- ## 3. Typical Applications * **Industrial Networking:** Managed switches and industrial PCs. * **Computing:** Motherboards and Network Interface Cards (NICs). * **IoT Gateways:** High-speed data collection hubs. * **Consumer Electronics:** Game consoles and Smart TVs. --- ## 4. Part Number Breakdown (Prefix) * **47:** Abracon LAN Series. * **LPQ:** Low Profile / High Performance Series. * **R:** Tape & Reel or RoHS Compliant (Packaging/Standard).
