## Detailed Technical Overview: FP1007R2-R12-R The **FP1007R2-R12-R** is a high-frequency, high-current power inductor designed by Eaton (formerly Cooper Bussmann). It belongs to the **FP1007 series** of Flat-Pac™ inductors, which are specifically engineered for multi-phase voltage regulator modules (VRMs). --- ### 1. Key Technical Specifications | Parameter | Value | Notes | | :--- | :--- | :--- | | **Inductance (L)** | 120 nH (0.12 µH) | Measured at 0Adc | | **Current Rating ($I_{rms}$)** | 61 A | Temperature rise current | | **Saturation Current ($I_{sat}$)** | 85 A | Based on 20% inductance drop | | **DCR (Direct Current Resistance)** | 0.29 mΩ | Typical value (very low) | | **Operating Temperature** | -40°C to +125°C | Includes self-heating | | **Tolerance** | ±10% | Standard for power inductors | | **Footprint** | 10.3mm x 7.0mm | Height: 7.0mm | --- ### 2. Design and Construction Features * **Core Material:** Uses a high-frequency ferrite core that minimizes core losses at high switching frequencies (up to 2MHz+). * **Winding Style:** Utilizes a "flat-pac" or foil-based winding. This provides a very large surface area for current flow, significantly reducing the **DC Resistance (DCR)**. * **Shielding:** The component is magnetically shielded, which prevents electromagnetic interference (EMI) from leaking into nearby sensitive circuits. * **Mounting:** Designed for Surface Mount (SMD/SMT) processes. --- ### 3. Common Applications This specific inductor is found in high-performance power delivery environments, including: 1. **Server CPU Power:** Multi-phase buck converters for Intel/AMD processors. 2. **GPUs:** High-end graphics card power delivery units. 3. **ASICs/FPGAs:** Used in networking and telecommunications equipment. 4. **DC-DC Converters:** High-density point-of-load (POL) modules. --- ### 4.
