Technical Specifications Table The following table breaks down the core electrical and physical characteristics of this specific component: | Feature | Specification | | :--- | :--- | | **Inductance** | 0.24 µH | | **Tolerance** | ±20% (indicated by 'M') | | **DC Resistance (DCR)** | ~1.60 mΩ (Typical) | | **Saturation Current (Isat)** | ~25.0 A | | **Temperature Rise Current (Irms)** | ~21.0 A | | **Dimensions (L x W x H)** | 7.4 x 6.8 x 3.0 mm | | **Operating Temperature** | -55°C to +125°C | --- ### 2. Part Number Decoder To understand how the component is categorized, we can break down the alphanumeric code: * **0630**: Represents the physical size (Case size). In this case, approximately 6.0mm x 6.0mm with a 3.0mm height. * **CDMC**: Indicates the series family (Shielded, metal compound core construction). * **CDS**: A sub-series designation related to the specific internal construction or termination style. * **R24**: The inductance value. `R` acts as a decimal point, meaning **0.24 microhenries (µH)**. * **M**: The tolerance code. `M` stands for **±20%**. * **C**: Typically indicates the packaging type (Carrier Tape/Reel). --- ### 3. Key Features & Construction * **Metal Compound Core:** Unlike traditional ferrite inductors, these use a metal powder molding technology. This allows for a "soft saturation" characteristic, meaning the inductance doesn't drop off sharply when the current increases. * **Magnetic Shielding:** The molded construction naturally shields the component, reducing Electromagnetic Interference (EMI) with surrounding components on the PCB. * **Low DCR:** The use of thick copper wire ensures minimal energy loss as heat, making it ideal for high-efficiency mobile and industrial electronics. --- ### 4. Common Applications * **Voltage Regulator Modules (VRM):** Used in CPUs and GPUs for stable power delivery. * **DC/DC Converters:** Found in laptop power circuits and telecommunications equipment. * **Battery Powered Devices:** High efficiency at high currents helps extend battery life in portable tech.
