The **0630CDMCCDS-R56** is a high-performance, surface-mount (SMD) power inductor commonly used in DC-DC converter applications. It belongs to the **CDMC** series manufactured by **Sumida**. Below is a detailed breakdown of its electronic specifications and characteristics. ### 1. Part Number Breakdown Understanding the nomenclature helps identify the physical and electrical constraints of the component: | Component Segment | Meaning | | :--- | :--- | | **0630** | Physical Size (approx. 6.0mm x 3.0mm) | | **CDMC** | Series name (Molded Power Inductor) | | **R56** | Inductance value: **0.56 µH** | --- ### 2. Key Technical Specifications The "0630" footprint is popular because it offers a balance between a small PCB area and high current handling. | Parameter | Value | | :--- | :--- | | **Inductance** | 0.56 µH | | **Tolerance** | Usually ±20% (M) | | **DC Resistance (DCR)** | Very low (typically < 10 mΩ) | | **Saturation Current (Isat)** | High (often ranging from 15A to 25A depending on specific revision) | | **Operating Temperature** | -40°C to +125°C (including self-heating) | | **Construction** | Metal compound molding (Shielded) | --- ### 3. Core Features * **Magnetic Shielding:** The part is "molded," meaning the coil is embedded in a magnetic metal powder. This provides excellent EMI (Electromagnetic Interference) shielding and reduces "buzz" noise. * **High Saturation:** Unlike traditional ferrite inductors, these molded inductors have a "soft saturation" characteristic. They do not lose inductance abruptly when current increases. * **Low Profile:** The "30" in 0630 indicates a maximum height of roughly 3.0mm, making it suitable for slim electronic devices. --- ### 4. Typical Applications This specific inductor (0.56 µH) is optimized for high-frequency switching regulators. * **Voltage Regulator Modules (VRM):** For CPUs and GPUs. * **Point of Load (POL) Converters:** Converting 12V or 5V down to 1.xV for digital logic. * **Battery Powered Devices:** Laptops, tablets, and high-end smartphones. * **Automotive Electronics:** Used in infotainment and ADAS sensors due to high temperature stability. --- ### 5. Footprint (Dimensions) * **Length:** ~7.0 mm (including terminals) * **Width:** ~6.6 mm * **Height:** ~3.0 mm
