The part number **0512CDMCCDS-R10MC** refers to a high-current, low-profile power inductor, typically manufactured by **Sumida**. These components are essential in modern electronics for managing power conversion and filtering. --- ### Part Number Breakdown | Component Segment | Meaning | Details | | :--- | :--- | :--- | | **0512** | Case Size | Dimensions approx. 5.4 x 5.2 mm; Height 1.2 mm | | **CDMC** | Series Type | Power Inductor (Metal Composite Core) | | **CDS** | Construction | Shielded construction for low EMI | | **R10** | Inductance Value | **0.10 µH** (R denotes decimal point) | | **M** | Tolerance | ±20% | | **C** | Application/Packaging | Specific automotive or industrial grade/reel info | --- ### Technical Specifications The 0512CDMC series is characterized by its "Metal Composite" core technology, which offers superior performance over traditional ferrite cores in specific applications. * **Inductance:** 0.10 µH * **DC Resistance (DCR):** Extremely low (typically < 3.0 mΩ), which minimizes power loss. * **Saturation Current (Isat):** Very high, usually ranging from 15A to 25A depending on temperature rise. * **Operating Temperature:** Typically -55°C to +125°C. * **Shielding:** Magnetically shielded to reduce electromagnetic interference (EMI). --- ### Key Features & Benefits 1. **High Saturation:** Unlike ferrite inductors that have a "hard" saturation point, metal composite cores have a "soft" saturation curve. This prevents sudden drops in inductance during current spikes. 2. **Compact Profile:** At only 1.2mm tall, it is ideal for thin devices like smartphones, tablets, and laptop VRMs (Voltage Regulator Modules). 3. **Efficiency:** The low DCR ensures minimal heating, which is critical for high-efficiency DC-DC converters. 4. **Low Noise:** The molded construction reduces acoustic noise caused by magnetostriction. --- ### Common Applications * **Voltage Regulator Modules (VRM):** Used in CPUs and GPUs to provide stable power. * **DC-DC Converters:** Buck, Boost, and Buck-Boost circuits. * **Consumer Electronics:** High-end laptops, SSDs, and handheld devices. * **Automotive:** Infotainment systems and ADAS sensors (if AEC-Q200 qualified). ---
