Based on the part number **580A331I-R1000**, this component is a **Power Inductor**, likely manufactured by a company like **ITG Electronics** or a similar high-current magnetic component specialist. These parts are typically used in high-frequency DC-DC converters, voltage regulator modules (VRMs), and server power supplies. --- ### Technical Specifications The part number follows a standard naming convention for high-current inductors. Here is the breakdown of the likely specifications: | Parameter | Estimated Value | Notes | | :--- | :--- | :--- | | **Inductance** | 100 nH (0.10 µH) | Represented by "1000" (100 x 10^0 nH) | | **Tolerance** | ±10% to ±20% | Standard for power inductors | | **Type** | High-Current / Molded | Designed for low DCR and high saturation | | **Mounting Type** | Surface Mount (SMD) | High-speed automated assembly | | **Applications** | VRM, EV, Computing | Used in multi-phase buck converters | --- ### Key Features 1. **High Saturation Current ($I_{sat}$):** Designed to handle massive spikes in current without the magnetic core "saturating" (losing its inductive properties). 2. **Low DCR (DC Resistance):** Uses flat wire or heavy gauge copper to minimize heat loss and maximize efficiency. 3. **Shielded Construction:** Usually features a magnetic metal powder core that provides self-shielding, reducing Electromagnetic Interference (EMI). 4. **Thermal Stability:** Rated for operation in harsh environments, often up to 125°C or 150°C. ### Physical Characteristics These inductors are often "block-style" or "molded" components. * **Terminals:** Typically feature wide pads on the bottom to handle high current. * **Core Material:** Usually a carbonyl iron or alloy powder core. --- ### Common Use Cases * **Graphics Cards (GPUs):** Providing stable power to high-performance processors. * **Server Motherboards:** In multi-phase power stages. * **Automotive Electronics:** Powering ADAS or infotainment systems.
