Technical Specifications The table below outlines the core electrical and physical characteristics of the component: | Parameter | Specification | Note | | :--- | :--- | :--- | | **Inductance** | 0.15 µH | Tolerance: ±20% | | **Rated Current (Isat)** | 7.7 A | Based on Inductance change | | **Rated Current (Itemp)** | 5.5 A | Based on Temperature rise | | **DC Resistance (DCR)** | 11 mΩ (Max) | Very low internal resistance | | **Dimensions (L x W)** | 2.0 x 1.6 mm | 0806 inch size | | **Thickness (T)** | 1.2 mm (Max) | Low profile | | **Operating Temp** | -40°C to 125°C | Industrial grade range | --- ### 2. Key Features and Construction * **Metal Alloy Core:** 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 molded construction provides excellent magnetic shielding, reducing Electromagnetic Interference (EMI) with surrounding components. * **High Current Density:** Due to the metal alloy material, it can handle significantly higher currents compared to ferrite inductors of the same physical size. --- ### 3. Part Number Breakdown Understanding the Murata nomenclature: | Code | Meaning | | :--- | :--- | | **DFE** | Series name (Metal Alloy Inductor) | | **201612** | Dimensions (2.0mm x 1.6mm x 1.2mm) | | **PD** | Internal characteristic code | | **R15** | Inductance value (R15 = 0.15 µH) | | **M** | Tolerance (M = ±20%) | | **P2** | Packaging code (typically Taping/Reel) | --- ### 4. Typical Applications Because of its small footprint and high current capability, this inductor is primarily used in: * **DC-DC Converters:** Point-of-Load (POL) modules in smartphones and tablets. * **Power Management Integrated Circuits (PMICs):** For CPU/GPU core voltage regulation. * **Wearable Devices:** Where board space is at a premium but power efficiency is critical.
