The **DFE252012F-R68M** is a high-performance, miniature power inductor manufactured by **Murata Electronics**. It belongs to the DFE252012F series, which is specifically designed for high-current applications in compact electronic devices like smartphones and tablets. --- ### ## Technical Specifications | Parameter | Specification | | :--- | :--- | | **Inductance** | 0.68 µH | | **Tolerance** | ±20% (M) | | **Case Size (Metric)** | 2520 (2.5mm x 2.0mm) | | **Height (Max)** | 1.2 mm | | **Rated Current (Isat)** | 4.8 A (based on Inductance change) | | **Rated Current (Itemp)** | 3.7 A (based on Temperature rise) | | **DC Resistance (DCR)** | 27 mΩ (Max) | | **Core Material** | Metal Alloy | | **Operating Temperature** | -40°C to +125°C | --- ### ### Key Features 1. **Metal Alloy Construction:** Unlike traditional ferrite inductors, this part uses a metal alloy powder core. This provides **soft saturation characteristics**, meaning the inductance drops gradually as current increases, rather than dropping sharply. 2. **Magnetic Shielding:** The structure is naturally shielded, which minimizes Electromagnetic Interference (EMI) with surrounding components on a dense PCB. 3. **Low Profile:** With a maximum height of 1.2mm, it is ideal for "slim" electronic designs. 4. **High Current Handling:** Despite its small footprint, the metal alloy core allows it to handle significantly higher currents than similarly sized ferrite inductors. --- ### ### Part Number Breakdown The part number follows a specific nomenclature: * **DFE**: Product Series (Metal Alloy Power Inductor) * **2520**: Dimensions (2.5mm length x 2.0mm width) * **12**: Height (1.2mm max) * **F**: Internal Code (Standard specification) * **R68**: Inductance Value (R68 = 0.68 µH) * **M**: Tolerance (M = ±20%) --- ### ### Typical Applications * **DC-DC Converters:** Used in Point-of-Load (POL) power supplies. * **Mobile Devices:** Power management modules for smartphones and wearables. * **CPUs/GPUs:** Providing stable voltage rails for high-speed processors.
