The **LSWM-453232-R68K-B** is a specific part number for a **Surface Mount Device (SMD) Wire-Wound Inductor**. These components are widely used in power management and signal filtering circuits. Below is a detailed breakdown of its electronic characteristics and nomenclature. --- ### 1. General Specifications Based on standard naming conventions for this series (typically manufactured by companies like Taiyo Yuden or Lattron), here are the technical parameters: | Parameter | Specification | | :--- | :--- | | **Component Type** | SMD Wire-Wound Chip Inductor | | **Inductance** | 0.68 µH | | **Tolerance** | ±10% (K) | | **Package Size** | 4532 (Metric) / 1812 (Imperial) | | **Mounting Type** | Surface Mount (SMT) | --- ### 2. Part Number Breakdown The alphanumeric code provides specific data about the component's physical and electrical properties: | Segment | Meaning | Description | | :--- | :--- | :--- | | **LSWM** | Series Series | Indicates a Wire-wound type inductor, often optimized for high currents. | | **453232** | Dimensions | **4.5mm x 3.2mm x 3.2mm** (Length x Width x Height). | | **R68** | Inductance Value | "R" acts as a decimal point. 0.68 microhenries (µH). | | **K** | Tolerance | **±10%** (Standard for power inductors). | | **-B** | Packaging/Special | Often denotes Bulk packaging or a specific lead-free/RoHS revision. | --- ### 3. Key Electronic Functions * **Energy Storage:** In DC-DC converters, it stores energy in a magnetic field during the "on" cycle and releases it during the "off" cycle. * **Noise Filtering:** High impedance at high frequencies allows it to filter out electromagnetic interference (EMI) or ripple from power supplies. * **Impedance Matching:** Used in RF circuits to ensure maximum power transfer between stages. --- ### 4. Typical Applications This specific size (1812/4532) is relatively large for a chip inductor, meaning it is designed for robustness: 1. **Power Supplies:** Buck/Boost converters in automotive or industrial electronics. 2. **Audio/Video:** Filtering circuits for high-fidelity signal processing. 3. **Communication:** Base stations or networking hardware where stable inductance is required. ---
