The **XFHCL2009-R60M** is a high-performance **SMD (Surface Mount Device) Shielded Power Inductor**. These components are specifically designed for high-current applications where space is limited and electromagnetic interference (EMI) must be minimized. --- ### 1. Part Number Breakdown Understanding the nomenclature helps identify the component's specifications: | Segment | Meaning | Details | | :--- | :--- | :--- | | **XFHCL** | Series Code | High-current, low-profile shielded inductor series. | | **2009** | Case Size | Approximate dimensions (e.g., ~2.0mm x 2.0mm, height 0.9mm). | | **R60** | Inductance Value | **0.60 µH** (Microhenries). | | **M** | Tolerance | **±20%** standard tolerance. | --- ### 2. Key Technical Specifications While exact values can vary slightly by manufacturer (often XFMRS or equivalent), the typical characteristics for a "2009-R60M" inductor are: * **Inductance:** 0.60 µH. * **Shielding:** Magnetically shielded construction (prevents magnetic flux from leaking and affecting nearby components). * **Core Material:** Usually a Metal Alloy or Carbonyl Powder (provides high saturation current). * **DC Resistance (DCR):** Very low (typically in the range of 15–30 mΩ) to minimize power loss. * **Isat (Saturation Current):** The current level where inductance drops by a specific percentage (e.g., 30%). For this size, it is usually between **3A to 5A**. * **Irms (Heating Current):** The continuous current that causes a specific temperature rise (usually 40°C). --- ### 3. Physical Features & Construction 1. **Low Profile:** The "09" in the name often denotes a height of less than 1.0mm, making it ideal for ultra-thin electronics like smartphones or tablets. 2. **Molded Construction:** The wire coil is usually embedded in a metallic powder composite. This makes the part more robust against mechanical shock and acoustic noise (buzzing). 3. **Flat Bottom:** Designed for automated pick-and-place SMT assembly. --- ### 4. Common Applications Due to its high current handling and small footprint, the XFHCL2009-R60M is commonly found in: * **DC-DC Converters:** Used in point-of-load (POL) power supplies. * **Mobile Devices:** Power management for CPUs/GPUs in smartphones and wearables. * **Solid State Drives (SSD):** Filtering and energy storage in compact storage modules. * **Laptops:** VRM (Voltage Regulator Module) circuits. ---
