The **XFHCL2010-R90M** is a high-performance **Surface Mount Device (SMD) Power Inductor**, commonly used in compact electronic circuits for power management and signal filtering. --- ## 🔍 Technical Specifications Below are the core electronic parameters for the XFHCL2010-R90M: | Parameter | Value / Specification | | :--- | :--- | | **Inductance** | 0.90 µH | | **Tolerance** | ±20% (indicated by the 'M') | | **Case Size** | 2010 (Metric: 2.0 x 1.0 mm) | | **Current Rating (Isat)** | Typically 1.5A - 2.5A (varies by specific load) | | **DC Resistance (DCR)** | Low (optimized for efficiency) | | **Shielding** | Magnetically Shielded | --- ## 🛠️ Key Electronic Features ### 1. Miniature Footprint The "2010" designation refers to its physical dimensions (2.0mm length by 1.0mm width). This makes it ideal for high-density PCB layouts such as smartphones, wearables, and IoT devices. ### 2. High Current Saturation ($I_{sat}$) Despite its small size, this component is designed to handle high peak currents without the inductance dropping significantly. This is achieved through advanced metal alloy or ferrite core compositions. ### 3. Magnetic Shielding The inductor is shielded to prevent **Electromagnetic Interference (EMI)**. This ensures that the magnetic field generated by the inductor does not interfere with nearby sensitive components like RF antennas or microcontrollers. --- ## 💡 Typical Applications * **DC-DC Converters:** Used in "Buck" or "Boost" converters to store energy and smooth output current. * **Voltage Regulator Modules (VRM):** Found in portable electronics to provide stable power to CPUs/GPUs. * **Noise Filtering:** Used in power supply lines to filter out high-frequency switching noise. --- ## 📑 Part Number Breakdown | Segment | Meaning | | :--- | :--- | | **XFHCL** | Manufacturer Series Series (Often High Current/Low Profile) | | **2010** | Dimensions (2.0mm x 1.0mm) | | **R90** | Inductance Value (R denotes decimal: 0.90 µH) | | **M** | Tolerance Code (M = ±20%) |
