The **XFHCL6-R10M** is a high-performance **Surface Mount (SMD) Power Inductor**, typically manufactured by brands like XFMRS or specialized magnetic component suppliers. It is designed for high-current applications where efficiency and low electromagnetic interference (EMI) are critical. ### Technical Specifications The following table outlines the primary electrical and physical characteristics based on standard industrial datasheets for this series: | Parameter | Specification | | :--- | :--- | | **Inductance** | 0.10 µH (100nH) | | **Tolerance** | ±20% (M code) | | **DC Resistance (DCR)** | Very Low (typically < 1.0 mΩ) | | **Saturation Current (Isat)** | High (often > 40A depending on package size) | | **Operating Temperature** | -40°C to +125°C | | **Construction** | Shielded, Composite Molded | | **Package Size** | "6" refers to the series footprint (approx. 6.6 x 7.3 mm) | --- ### Key Features #### 1. Composite Molded Construction The inductor is made using a metal alloy powder pressed around the coil. This "molded" design provides: * **Soft Saturation:** Unlike ferrite cores that drop inductance sharply at high currents, this part maintains performance more gradually. * **Shielding:** The construction inherently reduces EMI leakage, making it safe for dense PCB layouts. #### 2. High Current Density Due to the 0.10 µH (R10) value, this inductor is optimized for ultra-fast switching frequencies. It can handle high peak currents without overheating, making it ideal for modern power stages. #### 3. Low DCR The "R10M" variant focuses on minimizing direct current resistance, which reduces power loss ($P = I^2R$) and improves the overall efficiency of the power converter. --- ### Common Applications The XFHCL6-R10M is primarily used in DC-DC conversion circuits, specifically: * **Voltage Regulator Modules (VRM):** Supplying high current to CPUs and GPUs. * **Point of Load (POL) Converters:** Used in servers and telecommunications equipment. * **Battery Powered Systems:** Where high efficiency is required to extend battery life. * **Automotive Electronics:** Infotainment and driver assistance systems (if AEC-Q200 qualified). --- ### Part Number Breakdown * **XF:** Manufacturer prefix (e.g., XFMRS). * **HCL:** High Current Low-profile series. * **6:** Package/Frame size indicator. * **R10:** Inductance value ($0.10$ µH). * **M:** Tolerance code ($\pm 20\%$).
