The **DFE201612P-R24M=P2** (often abbreviated as DFE201612P-R24M) is a miniature, high-performance fixed inductor manufactured by **Murata Electronics**. It belongs to the metal alloy family of power inductors, specifically designed for high-density DC-DC converter applications. --- ### ## Technical Specifications Below are the primary electrical and physical characteristics of the component: | Parameter | Specification | Details | | :--- | :--- | :--- | | **Inductance** | 0.24 µH | Measured at 1MHz | | **Tolerance** | ±20% | Standard for power inductors | | **DC Resistance (DCR)** | 16 mΩ (Max) | Very low to minimize power loss | | **Rated Current (Isat)** | 5.3 A | Current at which inductance drops 30% | | **Rated Current (Itemp)** | 4.4 A | Current causing a 40°C temp rise | | **Package Size** | 2016 (0806) | 2.0mm x 1.6mm | | **Height** | 1.2 mm (Max) | Low profile for mobile devices | | **Material** | Metal Alloy | Magnetic iron powder core | --- ### ### Key Features 1. **Metal Alloy Technology**: Unlike traditional ferrite inductors, this part uses a metal alloy core. This allows for a **soft saturation** characteristic, meaning the inductance decreases gradually as current increases rather than dropping off sharply. 2. **High Current Density**: Despite its tiny footprint (2.0 x 1.6 mm), it can handle over 5 Amps of saturation current, making it ideal for modern power-hungry processors. 3. **Low Magnetic Flux Leakage**: The construction is magnetically shielded, which reduces Electromagnetic Interference (EMI) with surrounding components on a crowded PCB. 4. **Low DC Resistance**: The use of flat wire or optimized winding techniques keeps the DCR low, which improves the overall efficiency of the power supply. --- ### ### Typical Applications This inductor is primarily found in compact consumer electronics where space is at a premium: * **Smartphones & Tablets**: Used in the PMIC (Power Management IC) circuits for CPU/GPU cores. * **Wearables**: Ideal for smartwatches due to the ultra-low 1.2mm height. * **SSD Storage**: Used in the voltage regulation modules of solid-state drives. * **IoT Modules**: Provides efficient power conversion for low-power wireless sensors. --- ### ### Part Number Breakdown: `DFE201612P-R24M` * **DFE**: Murata series name (Metal Alloy Inductor). * **2016**: Dimensions (2.0mm x 1.6mm). * **12**: Maximum height (1.2mm). * **P**: Internal code for design/specification. * **R24**: Inductance value (R24 = 0.24 microhenries). * **M**: Tolerance (M = ±20%).
