The **XFHCL6MD-R24M** is a high-performance, surface-mount (SMD) power inductor commonly used in DC-DC converter applications. It belongs to a class of metal composite inductors designed for high current density and low magnetic leakage. --- ### 1. Key Technical Specifications The following table summarizes the primary electrical and physical characteristics of the component: | Parameter | Specification | | :--- | :--- | | **Inductance** | 0.24 µH | | **Tolerance** | ±20% | | **DC Resistance (DCR)** | ~1.30 mΩ (Typical) | | **Rated Current (Iat)** | ~25.0 A (Based on temperature rise) | | **Saturation Current (Isat)** | ~40.0 A (Based on inductance drop) | | **Operating Temperature** | -40°C to +125°C | | **Package Size** | Approx. 7.0 x 6.6 x 6.0 mm | --- ### 2. Physical Construction and Features * **Core Material:** It utilizes a **Metal Alloy Powder** core. Unlike traditional ferrite cores, metal composite cores provide a "soft saturation" characteristic, meaning the inductance decreases gradually as current increases rather than dropping abruptly. * **Shielding:** The part is **Magnetically Shielded**. The molded construction minimizes Electromagnetic Interference (EMI), making it suitable for high-density PCB layouts near sensitive components. * **Low DCR:** The use of flat or heavy-gauge wire inside the molding results in extremely low DC resistance, which minimizes power loss and heat generation during high-current operation. --- ### 3. Typical Applications The XFHCL6MD-R24M is specifically designed for power management in modern electronics where space is limited but current demands are high: 1. **Voltage Regulator Modules (VRMs):** Used in CPU and GPU power supplies for laptops and servers. 2. **DC-DC Converters:** High-efficiency buck converters for telecommunications equipment. 3. **Battery Powered Devices:** Ideal for handheld devices requiring high-current bursts with minimal energy loss. 4. **Automotive Electronics:** Used in infotainment and ADAS systems due to its robust thermal performance. --- ### 4. Part Number Breakdown (XFMRS Style) While naming conventions can vary slightly by manufacturer, the code generally follows this logic: * **XF:** Manufacturer prefix (likely XFMRS). * **HCL:** High Current Inductor Series. * **6MD:** Physical dimensions/Case size (approx 6mm-7mm footprint). * **R24:** Inductance value (R24 = 0.24 µH). * **M:** Tolerance (M = ±20%).
