The **0630CDMCDDS-R10MC** is a specific part number for a **Surface Mount (SMD) Power Inductor**, commonly manufactured by companies like Sumida. This component is designed for high-current applications where space and efficiency are critical. --- ### 1. Part Number Breakdown The nomenclature typically follows this structure: | Segment | Meaning | Detail | | :--- | :--- | :--- | | **0630** | Case Size | Approx. 6.0mm x 6.0mm x 3.0mm (standard footprint) | | **CDMCDDS** | Series Code | Shielded, metal composite construction for low noise | | **R10** | Inductance Value | **0.10 µH** (microhenries) | | **M** | Tolerance | **±20%** | | **C** | Packaging/Special | Often refers to tape and reel packaging | --- ### 2. Technical Specifications These components are known for their "Molded" or "Metal Composite" structure, which allows for higher saturation currents compared to traditional ferrite cores. | Parameter | Typical Value | | :--- | :--- | | **Inductance** | 0.10 µH | | **DC Resistance (DCR)** | Extremely low (often < 2.0 mΩ) | | **Saturation Current (Isat)** | Very high (typically 30A - 50A depending on heat rise) | | **Operating Temperature** | -55°C to +125°C (includes self-heating) | | **Shielding** | Magnetically shielded (Low EMI) | --- ### 3. Key Features * **Metal Composite Core:** Unlike ferrite inductors, these use a powdered iron/metal core which results in a "soft" saturation curve. This prevents a sudden drop in inductance during high-current spikes. * **Low DCR:** Because the inductance is very low (0.10 µH), the internal copper windings are thick, leading to minimal power loss and heat generation. * **Shielded Construction:** The molded design encapsulates the coil, significantly reducing electromagnetic interference (EMI) with surrounding components. --- ### 4. Common Applications This inductor is typically used in high-frequency DC-DC converters and Power Management Integrated Circuits (PMICs). * **Voltage Regulator Modules (VRM):** Used in CPU/GPU power delivery. * **Distributed Power Systems:** Point-of-Load (POL) converters. * **Consumer Electronics:** High-end laptops, tablets, and SSDs where compact size and high efficiency are required. ---
