The **FP2-D068-R** is a high-reliability, surface-mount power inductor manufactured by **Eaton (formerly Cooper Bussmann/Coiltronics)**. It is part of the FP2 series, designed specifically for high-frequency, high-current power applications. --- ### ## Technical Specifications The following table outlines the primary electrical and physical characteristics of the FP2-D068-R: | Parameter | Value | | :--- | :--- | | **Inductance** | 68 nH (0.068 µH) | | **Tolerance** | ±10% | | **Maximum Rated Current ($I_{rms}$)** | 28 Amps | | **Saturation Current ($I_{sat}$)** | 42 Amps | | **DC Resistance (DCR)** | 0.46 mΩ (Typical) | | **Operating Temperature** | -40°C to +125°C | | **Mounting Type** | Surface Mount (SMD/SMT) | | **Dimensions** | 7.2mm x 6.7mm x 5.0mm | --- ### ## Core Electronic Features ### 1. High Saturation Current The "D068" in the part number refers to its 68nH inductance. Despite the low inductance value, it is designed to handle very high peak currents (up to 42A) without the magnetic core saturating. This makes it ideal for transient-heavy environments. ### 2. Ultra-Low DCR With a DC resistance of only **0.46 mΩ**, this component minimizes power loss through heat (copper loss). This is critical for maintaining high efficiency in voltage regulator modules (VRMs). ### 3. Ferrite Core Material The FP2 series utilizes a ferrite core material. This ensures low core losses at high switching frequencies, which is essential for modern DC-DC converters operating in the MHz range. ### 4. Halogen Free and RoHS Compliant The part is designed for environmentally friendly manufacturing and is compatible with lead-free solder reflow profiles. --- ### ## Common Applications Because of its high current handling and compact footprint, the FP2-D068-R is typically found in: * **Multi-phase buck regulators:** Used in servers and networking equipment. * **Voltage Regulator Modules (VRM):** Powering CPUs and GPUs. * **Point-of-Load (POL) Converters:** Providing stable power to high-speed FPGAs. * **Graphics Cards:** Managing the high-current demands of high-end video processing units. ---
