The **DFE201612P-R24M=P2** is a high-performance, metal alloy power inductor manufactured by **Murata Electronics**. It is part of the DFE series, specifically designed for DC-DC converter applications where space is limited and high efficiency is required. --- ### ## Technical Specifications | Parameter | Specification | | :--- | :--- | | **Inductance** | 0.24 µH | | **Tolerance** | ±20% | | **Rated Current (Isat)** | 5.3 A (Max) | | **Rated Current (Itemp)** | 4.3 A (Max) | | **DC Resistance (DCR)** | 22 mΩ (Max) | | **Case Size (EIA)** | 0806 (Metric 2016) | | **Dimensions** | 2.0mm x 1.6mm x 1.2mm | | **Operating Temperature** | -40°C to +125°C | --- ### ### Key Features * **Metal Alloy Construction:** Unlike traditional ferrite inductors, this part uses a metal iron powder core. This allows for a **soft saturation characteristic**, meaning the inductance drops gradually as current increases rather than dropping off sharply. * **Magnetic Shielding:** The structure is naturally shielded, which minimizes Electromagnetic Interference (EMI) with surrounding components. * **Low Profile:** With a height of only 1.2mm, it is ideal for thin consumer electronics. * **High Current Handling:** Despite its small footprint (2.0mm x 1.6mm), it can handle significant saturation currents (up to 5.3A). --- ### ### Applications This component is primarily used in power management stages for: 1. **Smartphones and Tablets:** CPU and GPU power rails. 2. **Wearable Devices:** Smartwatches and fitness trackers. 3. **SSD/Storage:** Power regulation for high-speed memory. 4. **Compact DC-DC Modules:** High-frequency switching regulators. --- ### ### Internal Structure (Simplified) ```text [ Terminal ] <--- Conductive electrode | [ Metal Core ] <--- Iron powder mixed with resin | [ Copper Coil ] <--- Flat wire or thick round wire | [ Terminal ] <--- High-temperature solderable surface ```
