Key Technical Specifications | Parameter | Value | | :--- | :--- | | **Inductance (L)** | 100 nH (0.10 µH) | | **Tolerance** | ±10% | | **Rated Current ($I_{rms}$)** | 85 Amps | | **Saturation Current ($I_{sat}$)** | 85 Amps | | **DC Resistance (DCR)** | 0.29 mΩ (Typical) | | **Operating Temperature** | -40°C to +125°C | | **Package / Case** | Surface Mount (SMD) | | **Dimensions** | 10.2mm x 8.0mm x 6.0mm | --- ### 2. Physical Construction and Features * **Ferrite Core Material:** Uses a high-frequency ferrite material that minimizes core losses at high switching frequencies. * **Flat Wire Construction:** The internal winding uses flat copper wire, which significantly reduces DC resistance (DCR) and improves thermal efficiency compared to round wire. * **Shielded Design:** The inductor is magnetically shielded to prevent Electromagnetic Interference (EMI) from affecting surrounding sensitive components on the PCB. * **High Current Density:** Its physical footprint is optimized to handle extremely high current (85A) in a relatively small volume. --- ### 3. Applications The FP1006R2-R10-R is typically found in high-performance computing environments: * **Voltage Regulator Modules (VRMs):** Used in CPU/GPU power delivery for servers and workstations. * **Point-of-Load (POL) Converters:** Efficiently stepping down voltage near high-power chips. * **Data Centers:** Powering high-speed networking equipment and storage arrays. --- ### 4. Part Number Breakdown Understanding the suffix codes: * **FP1006:** The series designation (dimensions approx 10x8x6mm). * **R2:** Revision/Version code indicating specific internal design variations. * **R10:** Indicates the inductance value (R = decimal point; 10 = 0.10µH or 100nH). * **-R:** Indicates RoHS compliance (Lead-free). ---
