Key Technical Specifications | Parameter | Specification | Note | | :--- | :--- | :--- | | **Inductance** | 0.24 µH | ±20% Tolerance | | **Case Size (EIA)** | 0805 | Metric: 2012 (2.0 x 1.2 mm) | | **Height** | 1.0 mm | Low-profile design | | **Rated Current (Isat)** | 5.3 A | Based on Inductance Change (Max) | | **Rated Current (Itemp)** | 3.8 A | Based on Temperature Rise (Max) | | **DC Resistance (DCR)** | 26 mΩ | Max value | | **Core Material** | Metal Alloy | High saturation characteristics | --- ### 2. Core Technologies & Features * **Metal Alloy Construction:** Unlike traditional ferrite inductors, this part uses a metal powder core. This allows for a "soft saturation" characteristic, meaning the inductance drops gradually rather than abruptly when current increases. * **Magnetic Shielding:** The structure is naturally shielded, reducing Electromagnetic Interference (EMI) with surrounding components on the PCB. * **High Current Density:** Due to the metal core, it can handle significantly higher currents relative to its small 2.0mm x 1.2mm footprint compared to standard wire-wound inductors. --- ### 3. Typical Applications The DFE201210U-R24M is optimized for **DC-DC conversion** in space-constrained environments: * **Smartphones & Tablets:** Power management integrated circuits (PMIC) for CPUs and GPUs. * **Wearables:** Efficient power delivery for small batteries. * **SSD/Storage:** Voltage regulation for high-speed controllers. --- ### 4.
