The **XFHCL5-R68L** is a specific part number for a **High-Current Power Inductor**, typically manufactured by companies like XFMRS or similar electronic component specialists. These components are designed for high-frequency DC-DC converters and power management circuits. ### 1. Technical Specifications The part number follows a standard naming convention where the suffixes denote inductance and tolerance values. | Parameter | Value / Specification | | :--- | :--- | | **Inductance** | 0.68 µH (Indicated by "R68") | | **Tolerance** | ±15% or ±20% (Typically "L" or "M" suffix) | | **Component Type** | Shielded Surface Mount (SMD) Power Inductor | | **Material** | Composite Magnetic Iron Powder (High Saturation) | | **Operating Temp** | -40°C to +125°C (Standard industrial grade) | --- ### 2. Key Features * **High Saturation Current:** Designed to handle high peak currents without the inductance dropping significantly (magnetic saturation). * **Shielded Construction:** The inductor is magnetically shielded to minimize Electromagnetic Interference (EMI), which is critical for densely packed PCBs. * **Low DCR (DC Resistance):** Uses flat wire or heavy gauge copper to minimize power loss and heat generation. * **Soft Saturation Characteristics:** Unlike ferrite cores that drop inductance sharply, the powder core in this series provides a gradual roll-off. --- ### 3. Application Use Cases This component is commonly found in the following electronic environments: 1. **Voltage Regulator Modules (VRM):** Used in CPU/GPU power delivery on motherboards. 2. **Point of Load (POL) Converters:** Step-down (Buck) converters used in telecommunications. 3. **Battery Powered Devices:** High-efficiency power management for portable electronics. 4. **Automotive Infotainment:** Powering onboard displays and processing units. --- ### 4. PCB Footprint (Example) While you should always consult the specific datasheet for the **XFHCL5** series dimensions, the typical footprint for this class of inductor is: ```markdown Dimensions (approximate): - Length: 5.4 mm - Width: 5.2 mm - Height: 3.0 mm (Low profile) ```
