Core Features and Construction * **High Frequency Performance:** Designed for high switching frequencies (up to 2 MHz), making it ideal for modern power management ICs. * **Ferrite Core Material:** The use of a ferrite core ensures low core losses and stable performance across a wide frequency range. * **Flat-Wire Design:** The "FP" in the series often refers to a flat-wire construction which minimizes DC resistance (DCR) and optimizes the footprint for high current density. * **RoHS Compliant:** The "-R" suffix indicates that the part is lead-free and meets environmental standards. --- ### 3. Common Applications This specific inductor is found in high-performance computing environments where space is limited and power demands are extreme: * **Voltage Regulator Modules (VRMs):** Found on motherboards and GPU cards to step down voltage for CPUs and GPUs. * **Point-of-Load (POL) Converters:** Used in telecommunications and data centers. * **Servers and Workstations:** Essential for high-density power supply circuits. --- ### 4. Interpretation of Part Number The part number can be broken down as follows: * **FP1006:** Series name and package dimensions (approx. 10x6mm footprint). * **R2:** Revision or design variation (specific to the physical construction). * **R16:** Inductance value where "R" acts as a decimal point ($0.16 \mu H$). * **-R:** RoHS compliance suffix. ---
