The part number **0618CDMCCDS-R10MC** refers to a high-current, low-profile power inductor, typically manufactured by **Sumida** (CDMC series). These components are essential in modern electronics for voltage regulation and noise filtering. --- ### 1. Component Specifications Below is a breakdown of the technical characteristics typically associated with this part number: | Parameter | Value / Specification | | :--- | :--- | | **Inductance** | 0.10 µH (R10) | | **Tolerance** | ±20% (M) | | **Case Size** | 0618 (Approx. 7.2 x 6.6 mm) | | **Height** | 1.8 mm (Low Profile) | | **Core Material** | Metal Compound (Carbonyl Powder) | | **Shielding** | Magnetically Shielded | | **Mounting Type** | Surface Mount (SMD/SMT) | --- ### 2. Part Number Decoder Understanding the nomenclature helps in identifying variants within the same family: * **0618**: Represents the physical dimensions (Length/Width approx. 6.0-7.0mm, Height 1.8mm). * **CDMC**: The series designation (Metal Composite Power Inductor). * **R10**: The inductance value. "R" acts as a decimal point, so R10 = **0.10 µH**. * **M**: The tolerance code. M = **±20%**. * **C**: Internal manufacturing/packaging code. --- ### 3. Key Features & Applications #### Features * **High Saturation Current:** Metal composite cores handle high peak currents without sudden drops in inductance. * **Low DC Resistance (DCR):** Minimizes power loss and heat generation. * **Low Acoustic Noise:** The molded construction reduces buzzing sounds caused by magnetostriction. * **Shielded Construction:** Minimizes Electromagnetic Interference (EMI) with surrounding components. #### Common Applications * **DC/DC Converters:** Used in point-of-load (POL) power supplies. * **Computing:** CPU/GPU voltage regulator modules (VRMs) in laptops and tablets. * **Communication:** High-speed routers and base stations. * **Consumer Electronics:** Ultra-thin devices where vertical space is limited. --- ### 4. Comparison with Standard Inductors Compared to traditional ferrite drum core inductors, the **CDMC series** offers: 1. **Soft Saturation:** It loses inductance gradually as current increases, rather than "crashing" abruptly. 2. **Higher Energy Density:** More power handling in a smaller footprint.
