The **FP1007R2-R14-R** is a high-performance, high-current power inductor typically used in multi-phase voltage regulator modules (VRMs). It is part of the FP1007R series manufactured by Eaton (formerly Cooper Bussmann). --- ### 1. Technical Specifications The part number follows a specific nomenclature that defines its electrical characteristics. | Parameter | Value | | :--- | :--- | | **Inductance** | 0.14 µH (140 nH) | | **Current Rating ($I_{rms}$)** | 61 Amps | | **Saturation Current ($I_{sat}$)** | 85 Amps | | **DC Resistance (DCR)** | 0.29 mΩ (Max) | | **Operating Temperature** | -40°C to +125°C | | **Package Type** | Surface Mount (SMT) | | **Size/Dimension** | 10.2mm x 7.0mm x 7.0mm | --- ### 2. Key Features and Construction * **High Frequency Optimization:** Designed for high-speed switching frequencies (up to 2MHz), which is critical for modern power management. * **Ferrite Core Material:** Uses a high-density ferrite core to minimize core losses at high frequencies. * **Low DCR:** The extremely low DC resistance (0.29 mΩ) reduces power dissipation and improves overall efficiency in high-current applications. * **Flat-Wire Design:** The "FP" (Flat-Pac) designation refers to the flat-wire winding, which maximizes the copper fill factor and reduces skin-effect losses. --- ### 3. Common Applications This specific inductor is found in environments requiring high power density and stability: * **Computing:** Voltage Regulator Modules (VRMs) for CPUs and GPUs in servers and workstations. * **Data Centers:** High-current Point-of-Load (PoL) converters. * **Networking:** Routers and switches requiring stable power rails for ASICs/FPGAs. --- ### 4.
