The **FP1007R2B-R22-R** is a high-performance, high-current power inductor manufactured by Eaton (formerly Cooper Bussmann). It belongs to the FP1007 family, which is specifically designed for multi-phase voltage regulator modules (VRMs) and point-of-load (POL) converters. ### 1. Technical Specifications The part number encodes specific characteristics of the component. Below is the breakdown of its primary electrical properties: | Parameter | Value | | :--- | :--- | | **Inductance** | 215 nH (0.215 µH) | | **Tolerance** | ±10% | | **Current Rating (Irms)** | 61 Amps | | **Saturation Current (Isat)** | 85 Amps (at 25°C) | | **DC Resistance (DCR)** | 0.29 mΩ (Typical) | | **Operating Temperature** | -40°C to +125°C | | **Mounting Type** | Surface Mount (SMD) | --- ### 2. Key Features * **High Current Density:** Capable of handling significant current (up to 85A peak) in a very small footprint. * **Low DCR:** The ultra-low direct current resistance (0.29 mΩ) minimizes power loss and heat generation, increasing overall system efficiency. * **Flat-Wire Construction:** Uses a rectangular copper wire design which reduces "skin effect" losses at high frequencies. * **Ferrite Core Material:** Provides stable performance across a wide frequency range with low core losses. --- ### 3. Part Number Decoder The alphanumeric code follows a specific logic: | Segment | Meaning | | :--- | :--- | | **FP1007** | Product Series / Package Dimensions (approx. 10.2 x 7.0 x 7.0 mm) | | **R2B** | Revision/Internal Design Variation | | **R22** | Inductance value (R22 = 0.22 µH or 220 nH; actual spec is 215 nH) | | **-R** | RoHS Compliant / Lead-Free | --- ### 4.
