The **0630CDMCCDS-R56MC** is a specific part number for a surface-mount (SMD) power inductor. This component is widely used in power management circuits, such as DC-DC converters, to store energy and filter noise. --- ### 1. Part Number Breakdown Based on standard industry conventions (specifically aligned with manufacturers like Sumida), the part number can be decoded as follows: | Component Code | Meaning | Details | | :--- | :--- | :--- | | **0630** | Case Size | Approx. 6.6mm x 6.4mm x 3.0mm | | **CDM** | Series Type | Low profile, high current, metal compound core | | **CCDS** | Core Material | Shielded construction, often carbonyl iron | | **R56** | Inductance Value | **0.56 µH** (R denotes decimal point) | | **M** | Tolerance | **±20%** | | **C** | Packaging | Carrier Tape/Reel | --- ### 2. Technical Specifications The "0630" series typically features high efficiency and high current handling in a compact footprint. * **Inductance:** 0.56 µH. * **Current Rating (I-sat):** Typically very high (often between 15A - 25A depending on the specific series version), meaning the inductance won't drop significantly under heavy loads. * **DCR (DC Resistance):** Very low (usually < 5-10 mΩ), which minimizes power loss and heat generation. * **Operating Temperature:** Generally -40°C to +125°C (including self-heating). * **Shielding:** Magnetically shielded to prevent Electromagnetic Interference (EMI) with surrounding components. --- ### 3. Key Applications This specific inductor is designed for high-performance electronics where space is limited but power requirements are high: 1. **Voltage Regulator Modules (VRM):** Used in motherboards and GPU power phases. 2. **DC/DC Converters:** Buck or Boost converters for battery-powered devices. 3. **Laptops and Tablets:** Low-profile power supplies for CPUs. 4. **Networking Equipment:** High-current power distribution units. --- ### 4. Why "Metal Compound"? Unlike traditional ferrite inductors, the "CDM" series often uses a **metal powder core**. * **Advantage:** It offers a "soft saturation" characteristic. If the current exceeds the limit, the inductance decreases gradually rather than crashing abruptly, which prevents circuit failure.
