The **201610CDMCDDS-R68MC** is a high-performance, surface-mount (SMD) power inductor. This component is part of a series typically manufactured by companies like **Sumida**, designed for high-density power supply circuits. --- ### 1. Technical Specifications The part number follows a specific nomenclature that defines its electrical and physical characteristics. | Parameter | Value / Specification | | :--- | :--- | | **Inductance** | 0.68 µH | | **Tolerance** | ±20% (indicated by 'M') | | **Case Size** | 2.0mm x 1.6mm x 1.0mm | | **Material** | Metal Composite (Metal Alloy Powder) | | **Shielding** | Magnetic Shielded | | **Mounting Type** | Surface Mount (SMD/SMT) | --- ### 2. Key Features The construction of this inductor provides several advantages for modern electronics: * **Metal Composite Core:** Unlike traditional ferrite cores, the metal powder core offers "soft saturation" characteristics. This means the inductance drops gradually as current increases, rather than dropping sharply. * **Low Profile:** The "10" in the suffix often refers to the 1.0mm height, making it ideal for slim devices like smartphones and tablets. * **High Efficiency:** It is designed with low DC Resistance (DCR) to minimize power loss and heat generation. * **Magnetic Shielding:** The molded structure reduces Electromagnetic Interference (EMI), preventing the inductor from interfering with nearby sensitive components. --- ### 3. Applications This specific inductor is generally found in **DC-DC Converter** circuits where space is limited and high current handling is required. 1. **Mobile Devices:** Power management for CPUs and GPUs in smartphones. 2. **Wearables:** Smartwatches and fitness trackers. 3. **SSD Drives:** Power regulation for high-speed data storage. 4. **IoT Modules:** Compact wireless communication modules. --- ### 4.
