The part number **0624CDMCCDS-R68MC** refers to a high-current, low-profile **Power Inductor** manufactured by **Sumida**. These components are specifically designed for high-efficiency DC-DC converters and power modules. --- ### 1. Specification Overview The technical parameters of this specific inductor are detailed in the table below: | Parameter | Value | | :--- | :--- | | **Inductance** | 0.68 µH | | **Tolerance** | ±20% (indicated by 'M') | | **DC Resistance (DCR)** | ~4.1 mΩ (Max) | | **Saturation Current (Isat)** | ~18.0 A | | **Temperature Rise Current (Irms)** | ~13.5 A | | **Operating Temperature** | -55°C to +125°C | | **Construction** | Metal Compound (Shielded) | --- ### 2. Part Number Breakdown Understanding the nomenclature helps identify the physical and electrical characteristics: * **0624**: Refers to the physical size (Dimensions: Approx. 7.3 x 6.7 x 2.4 mm). * **CDMC**: Series name (Molded Power Inductor using metal powder). * **CDS**: Specific sub-series/design variation. * **R68**: The inductance value. "R" acts as a decimal point, so $0.68 \mu H$. * **M**: Tolerance code ($M = \pm 20\%$). * **C**: Packaging/Taping code. --- ### 3. Key Features & Materials * **Metal Powder Molding:** Unlike traditional wire-wound ferrite inductors, this part uses a metal powder core molded around the coil. This provides "soft saturation" characteristics, meaning the inductance doesn't drop off abruptly when current increases. * **Magnetic Shielding:** The molded structure naturally shields the component, reducing Electromagnetic Interference (EMI) with surrounding components. * **High Current Density:** The flat-wire or specialized winding technology allows for very low DCR, which minimizes power loss (heat) during operation. --- ### 4. Common Applications This inductor is typically found in: 1. **Notebooks and Tablets:** VRM (Voltage Regulator Module) for CPUs and GPUs. 2. **Server/Storage:** High-efficiency point-of-load (POL) converters. 3. **Automotive Infotainment:** Power supplies for displays and telematics. 4. **DC-DC Converters:** Buck/Boost regulators requiring low profile and high current capacity.
