The part number **0630CDMCCDS-R22MC** refers to a high-current, low-profile power inductor manufactured by **Sumida**. These components are specifically designed for surface-mount applications where efficiency and space are critical. --- ### 1. Technical Specifications Table | Parameter | Specification | | :--- | :--- | | **Inductance** | 0.22 µH | | **Tolerance** | ±20% (indicated by 'M') | | **Inductance Code** | R22 (0.22) | | **DCR (Direct Current Resistance)** | ~2.5 mΩ (typical) | | **Saturation Current (Isat)** | ~25.0 A - 30.0 A | | **Temperature Rise Current (Irms)** | ~18.0 A - 22.0 A | | **Operating Temperature** | -55°C to +125°C | | **Package Size** | 7.2 x 6.6 x 3.0 mm (approx.) | --- ### 2. Breakdown of the Part Number Understanding the nomenclature helps in identifying variants within the same series: * **0630**: Denotes the physical dimensions. Approximately **6.0mm x 6.0mm** footprint with a **3.0mm** height. * **CDMC**: Refers to the series type (Molded Power Inductor). * **CDS**: Specific construction or material subfamily (often Shielded). * **R22**: The inductance value. "R" acts as a decimal point, so R22 = **0.22 µH**. * **M**: The tolerance code. M = **±20%**. * **C**: Typically refers to the packaging type (e.g., Carrier Tape/Reel). --- ### 3. Key Features and Applications #### Construction The 0630CDMC series uses a **metal powder molding technology**. Unlike traditional wire-wound inductors with ferrite cores, these are encapsulated in a metal compound which provides: * **Magnetic Shielding:** Reduces Electromagnetic Interference (EMI). * **Soft Saturation:** The inductance doesn't drop off sharply when current increases. * **High Current Density:** High power handling in a small footprint. #### Common Applications * **DC/DC Converters:** Used in voltage regulator modules (VRMs). * **Laptops and Tablets:** High-efficiency power supplies for CPUs/GPUs. * **Automotive/Industrial:** Distributed power systems requiring robustness. * **LED Drivers:** Small-scale lighting power management. --- ### 4.
