The **XFHCL4LP-R82M** is a high-performance, shielded fixed inductor designed primarily for power management applications. It belongs to a category of surface-mount devices (SMD) often used in high-frequency DC-DC converters. --- ### 1. Technical Specifications The part number follows a specific nomenclature used by manufacturers (typically XFMRS) to define its electrical characteristics: | Parameter | Value | | :--- | :--- | | **Inductance** | 0.82 µH | | **Tolerance** | ±20% (indicated by 'M') | | **Inductor Type** | Power / Shielded | | **Mounting Type** | Surface Mount (SMD) | | **Package/Case** | LP (Low Profile) / CL4 Series | --- ### 2. Key Features * **Magnetic Shielding:** The "CL" series usually features a shielded construction, which minimizes Electromagnetic Interference (EMI) and protects sensitive surrounding components. * **Low Profile (LP):** Designed for compact electronics (smartphones, tablets, and thin IoT devices) where vertical space is limited. * **High Current Capability:** These inductors are engineered to handle high saturation currents without a significant drop in inductance. * **Low DCR:** It features low DC Resistance (DCR), which reduces power loss and improves overall energy efficiency. --- ### 3. Application Use Cases This component is commonly found in: 1. **Buck/Boost Converters:** Used for energy storage and filtering in voltage regulation circuits. 2. **Laptops and Peripherals:** Managing power delivery to CPUs and GPUs. 3. **Portable Electronics:** Battery-powered devices requiring efficient power stages and small footprints. 4. **Network Hardware:** Integrated into routers and switches for noise suppression. --- ### 4. Comparison with Similar Parts Compared to unshielded inductors, the **XFHCL4LP-R82M** provides: * **Better EMI performance:** Essential for passing regulatory certifications (FCC/CE). * **Higher Density:** Allows for tighter PCB layouts because the magnetic field is contained.
