The **XFTPRH106-R56N** is a specific surface-mount (SMD) power inductor. It is designed for high-current applications and is commonly used in DC-DC converters and power supply filtering. --- ### 1. Technical Specifications The part number follows a standard nomenclature used by manufacturers (typically XFMRS or similar brands). Below are the primary electrical and physical characteristics: | Parameter | Specification | | :--- | :--- | | **Inductance** | 0.56 µH (indicated by "R56") | | **Tolerance** | ±30% (indicated by "N") | | **Series Type** | RH106 (Shielded Power Inductor) | | **Dimensions** | Approx. 10mm x 10mm x 6mm | | **Core Material** | Ferrite | | **Shielding** | Magnetically Shielded | --- ### 2. Breakdown of the Part Number Understanding the code helps in identifying replacements or similar components: * **XF:** Manufacturer prefix (XFMRS). * **TP:** Type designation (likely referring to Tape & Reel packaging). * **RH106:** The series/size code. The "10" usually refers to a 10mm footprint, and "6" refers to a 6mm height. * **R56:** The inductance value. "R" acts as a decimal point. $0.56$ microhenries ($\mu H$). * **N:** Tolerance code. In the inductor industry, "N" typically represents $\pm 30\%$. --- ### 3. Key Features and Applications The XFTPRH106-R56N is engineered for performance in demanding environments: * **Magnetic Shielding:** The ferrite construction encloses the magnetic field, reducing Electromagnetic Interference (EMI) with neighboring components. * **High Current Handling:** Because the inductance is very low ($0.56\mu H$), this part is designed to handle high saturation currents, often found in high-frequency switching regulators. * **Low DCR:** It features low Direct Current Resistance (DCR), which minimizes power loss and heat generation. #### Common Uses: 1. **Motherboards:** Voltage Regulator Modules (VRMs) for CPUs. 2. **Power Supplies:** High-efficiency DC-DC step-down (Buck) converters. 3. **Graphics Cards:** Managing high-current power delivery. --- ### 4. Footprint/Layout Considerations When designing a PCB for this part, ensure the following: * **Thermal Relief:** Since this part handles high current, large copper pours are recommended to dissipate heat. * **Placement:** Keep the inductor close to the switching IC to minimize the current loop area and reduce noise.
