The **LSMT2-10050-R** is a high-performance, surface-mount (SMT) power inductor typically used in DC-DC converter circuits. It is designed to handle high currents while maintaining a compact footprint. --- ### 1. Key Technical Specifications The part number follows a standard nomenclature for power inductors. Below is a breakdown of its primary electronic characteristics: | Parameter | Specification (Typical) | | :--- | :--- | | **Inductance** | 0.50 µH (indicated by "050") | | **Tolerance** | ±20% | | **DC Resistance (DCR)** | Very Low (typically < 1.0 mΩ) | | **Saturation Current ($I_{sat}$)** | High (often 30A - 50A range) | | **Operating Temperature** | -40°C to +125°C | | **Package Size** | 10.0mm x 10.0mm x 5.0mm | --- ### 2. Physical & Material Construction * **Core Material:** Usually composed of a **Metal Alloy Powder**. This material provides "soft saturation" characteristics, meaning the inductance drops gradually rather than abruptly when the current exceeds the rated limit. * **Shielding:** It is a **Magnetic Shielded** design, which minimizes Electromagnetic Interference (EMI) with neighboring components on the PCB. * **Terminations:** Lead-free (RoHS compliant) tin plating over copper, designed for standard reflow soldering processes. --- ### 3. Functional Applications The LSMT2-10050-R is primarily used in power management stages where high efficiency and high current density are required: 1. **Voltage Regulator Modules (VRM):** Used in CPU and GPU power supplies for servers and workstations. 2. **Point-of-Load (POL) Converters:** Converting a high bus voltage down to lower voltages for digital ICs. 3. **High-Current DC-DC Converters:** Found in automotive infotainment and industrial control systems. 4. **Battery Powered Systems:** Where low DCR is critical to reducing power loss and extending battery life. --- ### 4. Part Number Breakdown While manufacturer codes vary slightly, the string generally decodes as follows: * **LSMT:** Series designation (Low-profile SMT). * **2:** Design revision or material type. * **10050:** Dimensions (10.0mm width/length, 5.0mm height). * **R:** Packaging (usually refers to Tape & Reel).
