The **DFP201610TV-R68M** is a high-performance, miniature metal alloy inductor commonly used in power management circuits. It is designed for high-density applications where space is limited and efficiency is critical. --- ### 1. Key Technical Specifications The part number provides specific details about its physical and electrical characteristics. | Parameter | Specification | | :--- | :--- | | **Inductance** | 0.68 µH | | **Tolerance** | ±20% (indicated by 'M') | | **Case Size** | 2016 (2.0mm x 1.6mm) | | **Height** | 1.0 mm (Max) | | **DC Resistance (DCR)** | Typ: 35 mΩ / Max: 42 mΩ | | **Rated Current (Isat)** | ~4.1 A (Saturation Current) | | **Rated Current (Itemp)** | ~3.3 A (Temperature Rise Current) | --- ### 2. Composition and Design The DFP series utilizes a **metal alloy core** rather than traditional ferrite. This provides several advantages: * **Soft Saturation:** Unlike ferrite inductors that drop inductance sharply when exceeding current limits, metal alloy cores saturate "softly," meaning the inductance decreases gradually. * **Magnetic Shielding:** The molded construction naturally shields the component, reducing Electromagnetic Interference (EMI) with surrounding components. * **Low Profile:** The "201610" designation confirms a footprint of 2.0mm x 1.6mm with a very low height of 1.0mm, making it ideal for mobile devices. --- ### 3. Common Applications These inductors are typically found in DC-DC converter circuits (Buck/Boost converters) for the following devices: 1. **Smartphones & Tablets:** Powering CPU/GPU rails where high current and small size are required. 2. **Wearables:** Optimized for smartwatches and IoT sensors where PCB real estate is at a premium. 3. **SSD/Storage:** Voltage regulation for high-speed data components. --- ### 4. Part Number Breakdown The nomenclature generally follows this logic: | Code Segment | Meaning | | :--- | :--- | | **DFP** | Series name (Molded Power Inductor) | | **201610** | Dimensions (2.0 x 1.6 x 1.0 mm) | | **TV** | Internal characteristic/packaging code | | **R68** | Inductance value (R68 = 0.68 µH) | | **M** | Tolerance (M = ±20%) |
