The **FDV0530S-R12M** is a high-performance, fixed power inductor typically manufactured by Murata (formerly TOKO). It is part of the FDV series, which is designed for high-current applications using metal alloy materials. --- ### 1. General Specifications Below is a technical breakdown of the component's parameters: | Parameter | Value | | :--- | :--- | | **Inductance** | 0.12 µH | | **Tolerance** | ±20% (M) | | **Rated Current (Isat)** | ~25.2 A (Saturation current) | | **Rated Current (Itemp)** | ~16.6 A (Temperature rise current) | | **DC Resistance (DCR)** | ~1.4 mΩ (Max) | | **Operating Temperature** | -40°C to +125°C | | **Construction** | Shielded, Metal Alloy Core | --- ### 2. Key Features * **Metal Alloy Technology:** Unlike traditional ferrite inductors, the metal alloy core allows for a "soft saturation" characteristic. This means the inductance drops gradually as current increases, rather than dropping sharply. * **Magnetic Shielding:** The molded construction provides excellent magnetic shielding, minimizing Electromagnetic Interference (EMI) with surrounding components. * **Low DCR:** The very low DC resistance (1.4 mΩ) ensures high efficiency and minimal heat generation during high-current operation. * **AEC-Q200 Qualified:** Most parts in this series are automotive grade, meaning they are tested for high vibration and thermal shock environments. --- ### 3. Physical Dimensions The part number "0530" refers to its footprint and height in millimeters: * **Length:** 6.2 mm (approx. including terminals) * **Width:** 5.8 mm * **Height:** 3.0 mm (Max) --- ### 4. Typical Applications This inductor is primarily used in DC-DC converters for high-density power systems, including: * **Notebooks and Tablets:** CPU/GPU core power supplies. * **Networking Equipment:** High-current Point-of-Load (POL) converters. * **Automotive:** Infotainment and Advanced Driver Assistance Systems (ADAS). --- ### 5.
