It is part of the FP1008R series manufactured by Eaton (formerly Cooper Bussmann). --- ## 1. Technical Specifications Below are the primary electrical and physical characteristics of this specific component: | Parameter | Value | | :--- | :--- | | **Inductance** | 150 nH (0.15 µH) | | **Tolerance** | ±10% | | **DC Resistance (DCR)** | 0.17 mΩ (typical) | | **Saturation Current ($I_{sat}$)** | 85 A | | **RMS Current ($I_{rms}$)** | 76 A | | **Operating Temperature** | -40°C to +125°C | | **Package / Case** | 10.2 x 8.0 x 8.0 mm (SMD) | --- ## 2. Part Number Breakdown Understanding the nomenclature helps identify the specific variant: * **FP1008R6:** The series designation. "1008" refers to the approximate footprint (10mm x 8mm), and "R6" refers to the version/revision. * **-R150:** Indicates the inductance value. `R150` = 0.150 µH (150 nanohenries). * **-R:** The suffix indicates that the part is **RoHS compliant**. --- ## 3. Key Features & Materials * **High Current Handling:** Designed specifically for low-voltage, high-current applications where power density is critical. * **Ferrite Core Material:** Uses a low-loss ferrite core to ensure high efficiency at high switching frequencies (up to 2 MHz+). * **Low DCR:** The extremely low DC resistance (0.17 mΩ) minimizes power loss due to heat (I²R losses), making it ideal for high-efficiency power supplies. * **Vertical Mount Design:** The "R" series often features a construction optimized for airflow and reduced PCB footprint. --- ## 4. Typical Applications These inductors are commonly found in: 1. **Server & Desktop CPUs:** Used in the Vcore power stages for Intel and AMD processors. 2. **Graphics Processing Units (GPUs):** High-end video cards require massive current at low voltages. 3. **Data Centers:** Point-of-Load (POL) converters and high-density DC-DC modules. 4. **Networking:** Large-scale routers and switches. ---
