The **FP1008R2-R180-R** is a high-frequency, high-current power inductor typically used in multi-phase Voltage Regulator Modules (VRMs) and DC-DC converters. It is part of the FP1008 series manufactured by **Eaton (formerly Cooper Bussmann)**. --- ### 1. Technical Specifications The following table summarizes the key electrical and physical characteristics of this component: | Parameter | Value / Specification | | :--- | :--- | | **Inductance** | 180 nH (0.18 µH) | | **Tolerance** | ±10% | | **DC Resistance (DCR)** | 0.17 mΩ (Typical) | | **Saturation Current ($I_{sat}$)** | ~80 Amperes | | **RMS Current ($I_{rms}$)** | ~68 Amperes | | **Operating Temperature** | -40°C to +125°C | | **Package / Case** | 10.2mm x 8.0mm x 8.0mm (SMD) | | **Core Material** | Ferrite | --- ### 2. Key Features * **High Current Density:** Designed to handle extremely high peak currents without saturating, making it ideal for modern CPU and GPU power delivery. * **Low DCR:** The exceptionally low direct current resistance (0.17 mΩ) minimizes power loss due to heat ($I^2R$ losses), improving overall system efficiency. * **Ferrite Core:** Utilizes a ferrite core material that provides low core losses at high switching frequencies (up to several MHz). * **Flat-Wire Construction:** The "R2" designation often refers to the specific winding or core geometry that optimizes the footprint-to-inductance ratio. --- ### 3. Common Applications This part is specifically engineered for high-performance computing environments: 1. **Server & Networking:** Used in point-of-load (POL) converters for data center processors. 2. **Graphics Cards:** High-end GPUs requiring stable, high-amperage power rails. 3. **Voltage Regulator Modules (VRM):** Multi-phase buck converters found on high-end motherboards. 4. **Desktop/Workstations:** Powering high-TDP (Thermal Design Power) CPUs. --- ### 4. Part Number Breakdown * **FP1008:** Product Series (dimensions approx. 10x8mm). * **R2:** Version/Revision code (specific to mechanical or material design). * **R180:** Inductance value (R = decimal point; 180 = 0.180 µH). * **-R:** RoHS compliant (Lead-free).
