The **CTXAL6030F-R56M** is a high-performance **Shielded Power Inductor** designed for surface mount (SMT) applications. It is part of the CTXAL series, typically manufactured by companies like Central Technologies, and is widely used in power conversion circuits. --- ## 1. Technical Specifications The part number itself follows a standardized nomenclature that defines its physical and electrical properties. | Parameter | Specification | | :--- | :--- | | **Inductance** | 0.56 µH (Microhenries) | | **Tolerance** | ±20% (indicated by 'M') | | **DC Resistance (DCR) Max** | ~2.5 mΩ to 3.5 mΩ (typical for this size) | | **Saturation Current (Isat)** | High (usually 15A - 25A depending on temp rise) | | **Package Size** | 6030 (approx. 6.0mm x 6.0mm x 3.0mm) | | **Shielding** | Magnetically Shielded | | **Mounting Type** | SMD/SMT (Surface Mount Device) | --- ## 2. Key Features ### A. Magnetic Shielding The component is constructed with a molded metal powder body. This design prevents electromagnetic interference (EMI) from leaking out and affecting surrounding components, making it ideal for high-density PCB layouts. ### B. High Current Handling Because it utilizes a flat wire or composite metal powder core, it offers very low DCR (DC Resistance). This minimizes power loss through heat, allowing it to handle high saturation currents without the inductance dropping off sharply. ### C. Compact Profile The "6030" footprint (6.0 x 6.0 mm with a 3.0 mm height) provides a balanced power-to-size ratio, suitable for modern portable electronics where vertical space is constrained. --- ## 3. Typical Applications This inductor is primarily used in **DC-DC Converters** and voltage regulation modules. * **Computing:** VRMs (Voltage Regulator Modules) for CPUs and GPUs. * **Consumer Electronics:** High-efficiency power supplies for laptops and tablets. * **Telecommunications:** Distributed power systems and base stations. * **Industrial:** High-current point-of-load (POL) converters. --- ## 4. Internal Construction The device typically consists of: 1. **Core Material:** Iron powder or alloy powder composite. 2. **Winding:** Copper wire (often flat wire to increase cross-sectional area and reduce resistance). 3. **Terminals:** Lead-free (RoHS compliant) tin-plated copper frame for easy soldering. ---
