The **XFHCL11HP-R36M** is a high-performance, surface-mount (SMD) power inductor commonly used in DC-DC converter applications. It belongs to a class of "Molded Power Inductors" designed for high current density and low acoustic noise. --- ### 1. Key Technical Specifications Based on the standard nomenclature for this series, here are the primary electrical and physical characteristics: | Property | Value / Description | | :--- | :--- | | **Inductance** | 0.36 µH (indicated by "R36") | | **Tolerance** | ±20% (indicated by "M") | | **Core Material** | Composite / Carbonyl Iron Powder | | **Shielding** | Magnetically Shielded (Molded construction) | | **Mounting Type** | Surface Mount (SMD/SMT) | | **Application** | High-current power supplies, VRMs, and DC-DC converters | ### 2. Part Number Breakdown Understanding the alphanumeric code helps identify the specific capabilities of the component: * **XF:** Manufacturer prefix (typically XFMRS or similar generic branding). * **HCL:** High Current Low Profile series. * **11HP:** Refers to the physical frame size (approximately 11mm x 10mm) and High Power rating. * **R36:** The inductance value where 'R' acts as a decimal point (0.36 microhenries). * **M:** Tolerance code for ±20%. ### 3. Core Advantages 1. **High Saturation Current:** The molded iron powder core allows the inductor to handle high peak currents without the inductance dropping off sharply (soft saturation). 2. **Low DCR:** It features low Direct Current Resistance, which minimizes power loss and heat generation. 3. **Low EMI:** Because the coil is fully encapsulated in a magnetic composite material, it provides excellent self-shielding, reducing electromagnetic interference with nearby components. 4. **Acoustic Quietness:** The molded structure reduces the "buzzing" noise (magnetostriction) often found in traditional wire-wound inductors. --- ### 4. Common Applications This component is typically found in: * **Voltage Regulator Modules (VRMs)** for CPUs and GPUs. * **High-efficiency DC-DC converters** (Buck, Boost, or Buck-Boost). * **Automotive infotainment** and industrial power systems. * **Battery-powered devices** where space and thermal efficiency are critical.
