The **AWP201610AF-R68M** is a high-performance **Surface Mount Device (SMD) Power Inductor**, commonly used in compact consumer electronics for DC-DC conversion and power management. --- ## 1. Part Number Breakdown Understanding the nomenclature helps identify its physical and electrical characteristics: | Code Segment | Meaning | Description | | :--- | :--- | :--- | | **AWP** | Series Name | High-current power inductor series (often alloy-based). | | **201610** | Dimensions | Metric size: **2.0mm x 1.6mm** with a **1.0mm** height. | | **AF** | Material/Type | Specific core material formulation (e.g., metal alloy for high saturation). | | **R68** | Inductance Value | **0.68 µH** (Microhenries). | | **M** | Tolerance | **±20%** tolerance. | --- ## 2. Key Electrical Specifications While exact values can vary slightly by manufacturer (e.g., Cyntec, Sunlord, or Delta), the standard specifications for this part size/value are generally as follows: * **Inductance:** 0.68 µH * **DC Resistance (DCR):** Typically low (~35mΩ to 50mΩ) to minimize power loss. * **Saturation Current (Isat):** The current at which inductance drops by ~30%. Usually ranges from **3.5A to 4.5A**. * **Heat Rating Current (Irms):** The current causing a 40°C temperature rise. Usually ranges from **3.0A to 4.0A**. * **Operating Temperature:** Generally **-40°C to +125°C**. --- ## 3. Core Technology and Benefits The "AWP" series typically utilizes **Metal Alloy Powder** rather than traditional ferrite. ### Advantages: * **Soft Saturation:** Unlike ferrite cores that drop inductance sharply when overloaded, metal alloy cores provide a gradual decline, enhancing circuit stability. * **High Current Density:** The 2016 (metric) footprint is very small, but the alloy core allows it to handle much higher currents than older technologies. * **Low EMI:** Most units are magnetically shielded to prevent electromagnetic interference with surrounding components (like sensitive RF circuits). * **Low DCR:** Efficient energy transfer with minimal heat generation. --- ## 4. Common Applications This inductor is typically found in the "Buck Converter" (Step-down) stages of: 1. **Smartphones:** Powering the CPU, GPU, or WiFi modules. 2. **Wearables:** Smartwatches and fitness trackers where space is at a premium. 3. **SSD/Storage:** Power regulation for high-speed data controllers. 4. **IoT Devices:** Battery-operated sensors requiring high efficiency. ---
