The **XFHCL5-R87** is a specific electronic component, typically categorized as a **High-Current Power Inductor** (specifically a shielded SMD inductor). These components are essential in power management circuits to store energy in a magnetic field and filter noise. --- ### 1. Technical Specifications While exact specifications can vary slightly by manufacturer (often associated with brands like XFMRS or specialized magnetic component suppliers), the "R87" nomenclature typically refers to its inductance value. | Feature | Specification (Typical) | | :--- | :--- | | **Inductance** | 0.87 µH (Microhenries) | | **Type** | Shielded Surface Mount (SMD) | | **Material** | Metal Composite or Ferrite Core | | **Mounting Type** | Surface Mount Technology (SMT) | | **Shielding** | Magnetically shielded to reduce EMI | --- ### 2. Key Characteristics * **Low DCR (DC Resistance):** Designed to have minimal internal resistance to prevent energy loss through heat, making it highly efficient. * **High Saturation Current:** The "High-Current" designation means the inductor can handle significant amperage before its magnetic core saturates and loses inductance. * **Magnetic Shielding:** The internal construction prevents electromagnetic interference (EMI) from affecting nearby sensitive components on the PCB. * **Compact Footprint:** Part of the "CL" or low-profile series, designed for dense circuit boards in portable electronics. --- ### 3. Common Applications The XFHCL5-R87 is primarily used in **DC-DC Converters** and voltage regulation modules. * **Voltage Regulator Modules (VRM):** Used in CPUs and GPUs to stabilize high-current power delivery. * **Battery Powered Devices:** Laptops, tablets, and smartphones where power efficiency is critical. * **POL (Point of Load) Converters:** Converting a main power rail (e.g., 12V) down to lower voltages (e.g., 1.2V or 3.3V) for ICs. --- ### 4. Circuit Identification In a schematic or on a Printed Circuit Board (PCB), this part will be represented as follows: ```text Reference Designator: L (e.g., L101, L204) Symbol: ---(nnnn)--- (A series of curved humps representing a coil) ```
