The **MHO351FAD-R** is a specific electronic component, typically categorized as a **Surface Mount Device (SMD) Power Inductor**. These parts are essential in power management circuits for filtering and energy storage. --- ## 1. Component Overview The part number follows a standard nomenclature used by manufacturers (like Delta or similar magnetic component producers). Here is the breakdown of its core characteristics: | Feature | Description | | :--- | :--- | | **Component Type** | Shielded Power Inductor | | **Mounting Type** | Surface Mount (SMD/SMT) | | **Construction** | Metal Alloy / Magnetic Shielded | | **Application** | DC-DC Converters, Voltage Regulator Modules (VRM) | --- ## 2. Key Specifications While exact values can vary slightly by manufacturer series, the "351" series typically defines the physical footprint. ### A. Electrical Characteristics * **Inductance:** Usually indicated by the suffix (though "FAD" is a series code). Standard values in this series range from **0.22µH to 2.2µH**. * **Current Rating:** High current capability, often ranging from **15A to 40A** depending on the specific inductance value. * **DCR (DC Resistance):** Extremely low resistance to minimize power loss and heat generation. ### B. Physical Dimensions (Approximate) The "35" in the prefix often refers to the metric or imperial sizing of the package: * **Length:** ~4.0 mm * **Width:** ~4.0 mm * **Height:** ~1.2 mm to 2.0 mm (Low profile) --- ## 3. Common Applications The MHO351FAD-R is designed for high-efficiency environments: 1. **Computing:** Motherboards, Graphics cards (GPU power stages), and Servers. 2. **Portable Electronics:** High-end smartphones and tablets requiring compact power delivery. 3. **Point of Load (POL):** Converters that step down voltage right next to the CPU/SoC. --- ## 4. Features & Benefits * **Magnetic Shielding:** Reduces Electromagnetic Interference (EMI) with surrounding components. * **High Saturation:** The metal alloy core allows the part to handle high peak currents without the inductance dropping sharply. * **RoHS Compliant:** The "-R" suffix usually denotes **RoHS Compliance**, meaning it is free from hazardous substances like lead. ---
