Key Technical Specifications The alphanumeric code provides specific details about the component's performance characteristics. | Parameter | Specification | | :--- | :--- | | **Inductance** | 185 nH (0.185 µH) | | **Tolerance** | ±10% | | **Full Load Current ($I_{sat}$)** | ~70A - 90A (Saturation current depends on temp rise) | | **DC Resistance (DCR)** | ~0.19 mΩ (Typical) | | **Operating Temperature** | -40°C to +125°C | | **Package Size** | 15.0mm x 7.5mm x 7.0mm | --- ### 2. Core Features and Construction * **Flat-Pac™ Technology:** This series uses a flat-wire construction. This reduces "skin effect" losses at high frequencies and allows for extremely low DCR (Direct Current Resistance), which minimizes power loss as heat. * **Magnetic Shielding:** The part is magnetically shielded to minimize Electromagnetic Interference (EMI), making it suitable for densely packed circuit boards. * **High Saturation:** It is engineered to handle high peak currents without the inductance dropping significantly, which is critical for stable power delivery. --- ### 3. Common Applications This specific inductor is typically found in high-performance computing environments: 1. **Multi-phase Vcore Regulators:** Used in motherboards and servers to provide power to CPUs and GPUs. 2. **Voltage Regulator Modules (VRMs):** Essential for converting high-voltage DC to the low-voltage, high-current DC required by processors. 3. **Point-of-Load (POL) Converters:** Used in telecommunications and networking equipment. 4. **Data Centers:** High-efficiency power supplies for storage and memory arrays. --- ### 4. Footprint and Mounting The device is an **SMD (Surface Mount Device)**. Its footprint is rectangular (15mm x 7.5mm), and it is designed for automated pick-and-place assembly. ```markdown Pinout Configuration: [ Terminal 1 ] --- [ Inductor Coil ] --- [ Terminal 2 ] ``` ---
