The **0410CDMCCDS-R47MC** is a specific part number for a **Surface Mount Device (SMD) Power Inductor**, manufactured by **Sumida**. These components are essential for voltage regulation and energy storage in modern electronics. --- ## 1. Technical Specifications Breakdown The part number provides detailed information about the component's physical and electrical characteristics: | Parameter | Specification | Description | | :--- | :--- | :--- | | **Series** | 0410CDMCCDS | Shielded SMD Power Inductor (Automotive Grade) | | **Inductance** | 0.47 µH | Measured at 100kHz | | **Tolerance** | ±20% | Denoted by the "M" at the end | | **Case Size** | 4.4 x 4.0 x 1.0 mm | Compact footprint (Length x Width x Height) | | **DCR (Resistance)** | ~11.5 mΩ (Max) | DC Resistance (lower is better for efficiency) | | **Saturation Current** | ~11.0 A | Current at which inductance drops by 30% | | **Temperature Range** | -55°C to +155°C | High-temperature stability | --- ## 2. Key Features ### Metal Composite Construction Unlike traditional ferrite inductors, this part uses a **metal powder core**. This allows for: * **Soft Saturation:** The inductance decreases gradually as current increases, rather than dropping off sharply. * **High Current Density:** Handles more power relative to its small physical size. ### Magnetic Shielding The component is magnetically shielded, which minimizes **Electromagnetic Interference (EMI)**. This is crucial for dense circuit boards where components are packed closely together. ### Automotive Grade (AEC-Q200) The "CDS" designation often refers to parts qualified for automotive applications, meaning they can withstand extreme vibrations, thermal shocks, and high operating temperatures. --- ## 3. Typical Applications This inductor is primarily used in **DC-DC Converters** and **Voltage Regulator Modules (VRMs)**. Common applications include: * **Infotainment Systems:** Powering screens and processors in vehicles. * **Advanced Driver Assistance Systems (ADAS):** Cameras and radar sensors. * **Mobile Devices:** High-efficiency power management for smartphones and tablets. * **LED Drivers:** Providing stable current for lighting systems. --- ## 4.
