The part number **0624CDMCCDS-R10MC** refers to a high-current, low-profile power inductor, typically manufactured by **Sumida**. These components are widely used in DC-DC converters for laptops, servers, and automotive electronics due to their high efficiency and compact size. --- ### 1. Part Number Breakdown The alphanumeric code provides specific details about the component's physical and electrical characteristics: | Code Segment | Meaning | Description | | :--- | :--- | :--- | | **0624** | Size Code | Dimensions: approx. 6.0 x 6.0 mm (Footprint) x 2.4 mm (Height) | | **CDMC** | Series | Indicates a Power Inductor with a metal composite core | | **CDS** | Construction | Standard shielded construction for low EMI | | **R10** | Inductance | **0.10 µH** (R denotes the decimal point) | | **M** | Tolerance | **±20%** inductance tolerance | | **C** | Packaging/Custom | Usually refers to Taping/Reel packaging | --- ### 2. Technical Specifications While exact values can vary slightly by manufacturer batch, the typical specifications for this 0.10µH inductor are: * **Inductance:** 0.10 µH * **DC Resistance (DCR):** Extremely low (typically < 2.0 mΩ) to minimize power loss. * **Saturation Current ($I_{sat}$):** Very high (often > 25A), meaning the inductance stays stable even under heavy load. * **Operating Temperature:** Typically -40°C to +125°C. * **Core Material:** Metal powder (Iron powder/Composite), which offers "soft saturation" characteristics. --- ### 3. Key Features & Benefits * **Magnetic Shielding:** The molded metal powder construction naturally shields the component, reducing Electromagnetic Interference (EMI) with surrounding circuits. * **High Current Density:** Capable of handling significant amperage relative to its small surface-mount footprint. * **Low Buzz Noise:** The molded construction minimizes acoustic noise caused by magnetostriction. --- ### 4. Common Applications This specific part is designed for high-frequency switching environments: 1. **Voltage Regulator Modules (VRMs):** Powering CPUs and GPUs. 2. **Point of Load (POL) Converters:** Distributed power systems on motherboards. 3. **Battery Powered Devices:** Where high efficiency and low heat generation are critical.
