Technical Specifications The part number encodes specific electrical and physical characteristics: | Parameter | Specification | Details | | :--- | :--- | :--- | | **Inductance** | 0.56 µH | Indicated by "R56" | | **Tolerance** | ±20% | Indicated by "M" | | **Case Size** | 2016 (Metric) | 2.0mm x 1.6mm | | **Height** | 1.2mm Max | Indicated by "12" | | **Material** | Metal Alloy | Low DCR and high saturation current | | **Structure** | Molded | Shielded construction for low EMI | --- ### 2. Key Features * **High Current Handling:** Due to the metal powder core, it can handle higher saturation currents compared to traditional ferrite inductors of the same size. * **Magnetic Shielding:** The molded construction minimizes electromagnetic interference (EMI), which is critical for densely packed circuit boards. * **Soft Saturation:** Unlike ferrite inductors that drop inductance sharply when saturated, metal alloy inductors show a gradual (soft) saturation curve. * **Low DC Resistance (DCR):** Optimized to reduce power loss and heat generation, increasing overall battery life in portable devices. --- ### 3. Application Use Cases This component is primarily used in **DC-DC Converter** circuits. Specific applications include: 1. **Smartphones & Tablets:** Powering CPUs, GPUs, and Wi-Fi modules. 2. **Wearables:** Smartwatches and fitness trackers where space is at a premium. 3. **SSD/Storage:** Voltage regulation for high-speed data drives. 4. **IoT Devices:** Providing efficient power management for small-form-factor sensors. --- ### 4. Comparison: Ferrite vs. Metal Alloy (DFP Series) | Feature | Ferrite Inductor | DFP201612NV-R56M (Metal) | | :--- | :--- | :--- | | **Saturation** | Sharp drop-off | Gradual (Soft) saturation | | **Size** | Larger for same current | Ultra-compact | | **EMI** | Higher leakage | Very low (Shielded) | | **Efficiency** | Good at low loads | Excellent at high loads |
