The **DFP201610TV-R33M** is a high-performance, metal alloy core surface-mount inductor (SMD), typically manufactured by companies like Cyntec or Toko (Murata). It is designed primarily for power management circuits where space is limited and high current handling is required. ### 1. Part Number Deciphering Understanding the nomenclature helps identify the physical and electrical constraints of the component: | Component Segment | Meaning | Details | | :--- | :--- | :--- | | **DFP** | Series Name | Metal alloy inductor series (low profile/high current). | | **2016** | Dimensions (Metric) | 2.0 mm x 1.6 mm footprint. | | **10** | Height | 1.0 mm maximum thickness. | | **TV** | Internal Code | Specific process or material characteristic (AEC-Q200 qualified variants often use similar suffixes). | | **R33** | Inductance Value | **0.33 µH** (R denotes the decimal point). | | **M** | Tolerance | **±20%** tolerance. | --- ### 2. Key Electrical Specifications Based on standard data for the 0.33µH variant in the 201610 package: | Parameter | Typical Value | | :--- | :--- | | **Inductance** | 0.33 µH | | **DC Resistance (DCR)** | ~18 - 22 mΩ (Max) | | **Saturation Current (Isat)** | ~5.5 A to 6.5 A (based on 30% drop in L) | | **Temperature Rise Current (Irms)** | ~4.0 A to 4.5 A (based on 40°C rise) | | **Operating Temperature** | -40°C to +125°C | --- ### 3. Core Technology and Features The "Metal Alloy" construction provides several advantages over traditional ferrite inductors: * **Soft Saturation:** Unlike ferrite cores that lose inductance abruptly when current limits are exceeded, metal alloy cores have a "soft" saturation curve. This prevents sudden spikes in circuit current. * **High Current Density:** The composite metal powder allows for a higher magnetic flux density, enabling high current ratings in a tiny 2016 (0806 inch) footprint. * **Magnetic Shielding:** The molded construction naturally acts as a magnetic shield, reducing Electromagnetic Interference (EMI) with neighboring components. * **Low DCR:** Efficient winding and material selection minimize power loss through heat. --- ### 4. Typical Applications This inductor is commonly found in DC-DC converter circuits (Buck/Boost) for: 1. **Smartphones and Tablets:** Core power supply for CPUs and GPUs. 2. **SSD/Storage:** Power rails for high-speed controllers. 3. **Wearables:** Compact power management modules. 4. **IoT Devices:** Where high efficiency and small form factors are critical. ---
