The **ALTG-832-R** is a high-performance, ultra-compact 10/100/1000 Base-T Single Port Transformer module, commonly used in networking hardware. It serves as the physical interface (PHY) between a networking chip and the RJ45 connector. --- ### 1. Key Technical Specifications The following table outlines the primary electrical and mechanical characteristics of the ALTG-832-R: | Parameter | Specification | | :--- | :--- | | **Type** | Lan Transformer / Magnetic Module | | **Data Rate** | 10/100/1000 Mbps (Gigabit Ethernet) | | **Turns Ratio** | 1:1 (Transmitter & Receiver) | | **Isolation Voltage** | 1500 Vrms | | **Insertion Loss** | -1.1 dB Max (1-100MHz) | | **Return Loss** | -18 dB Min (1-30MHz) | | **Operating Temp** | -40°C to +85°C (Industrial Grade) | | **Configuration** | Surface Mount (SMD) | --- ### 2. Core Functional Components The "Electronic Parts" within this module consist of a series of magnetic components housed in a single resin-molded package: 1. **Isolation Transformers:** These provide galvanic isolation between the internal circuitry and the external network cable. This protects the sensitive PHY chip from static discharge and surges. 2. **Common Mode Chokes (CMC):** Integrated into the module to suppress Electromagnetic Interference (EMI). They filter out high-frequency noise while allowing the data signal to pass through. 3. **Center Tap Capacitors:** Often used in conjunction with "Bob Smith" terminations to reduce common-mode emissions. --- ### 3. Application and Usage The ALTG-832-R is typically found in the following hardware environments: * **Embedded Systems:** Single-board computers (SBCs) or IoT gateways. * **Networking Gear:** Switches, routers, and Network Interface Cards (NICs). * **Industrial Automation:** PLCs and industrial Ethernet controllers requiring high temperature resistance. --- ### 4. Circuit Implementation Example In a standard PCB layout, the part is placed between the Ethernet Controller (PHY) and the RJ45 Jack. ```text [PHY Chip] <---> [ALTG-832-R Transformer] <---> [RJ45 Connector] ^ ^ ^ Digital Magnetic Physical Signals Isolation Media ``` ---
