The **XFHCL4LP-R10M** is a high-performance, low-profile surface-mount (SMD) power inductor. It is designed for high-current applications where space and efficiency are critical, such as DC-DC converters and power modules. --- ### 1. Key Technical Specifications The part number typically breaks down into the series, physical dimensions, and electrical values. | Parameter | Specification | | :--- | :--- | | **Inductance** | 0.10 µH (indicated by "R10") | | **Tolerance** | ±20% (indicated by "M") | | **Inductor Type** | Shielded, Composite/Molded Power Inductor | | **Current Rating (Isat)** | Typically 15A - 25A (High Saturation) | | **DC Resistance (DCR)** | Ultra-low (typically < 1.0 mΩ) | | **Operating Temperature** | -40°C to +125°C | --- ### 2. Physical Construction The "LP" in the part number stands for **Low Profile**, which is essential for modern thin electronics. * **Molded Structure:** It uses a metal alloy powder core molded around the copper coil. This construction allows for "soft saturation," meaning the inductance doesn't drop off instantly when high current is applied. * **Shielding:** The magnetic field is contained within the molded body, reducing Electromagnetic Interference (EMI) with surrounding components. * **Terminal Design:** Solder pads are located on the bottom of the component for a compact footprint. --- ### 3. Applications and Use Cases Because of its very low inductance (0.10 µH) and high current capability, this part is ideal for high-frequency switching environments. * **Voltage Regulator Modules (VRMs):** Found in CPU and GPU power delivery systems. * **DC-DC Converters:** Point-of-Load (POL) converters for high-speed telecommunications equipment. * **Battery Powered Devices:** Used in laptops and tablets where height constraints are strict. * **Server Power:** Handling high transient loads with minimal heat loss. --- ### 4. Part Number Breakdown (Typical) | Segment | Meaning | | :--- | :--- | | **XF** | Manufacturer prefix (likely XFMRS or similar brand) | | **HCL4** | Series identifier (High Current, Low Profile, Size Class 4) | | **LP** | Low Profile physical package | | **R10** | Inductance value (0.10 microhenries) | | **M** | Tolerance (±20%) |
