The **47LPA-150YR-R** is a specific electronic component typically categorized as a **Low-Profile Power Inductor**. These parts are designed for high-density power management circuits where vertical space is limited. --- ### ## Technical Specifications Below are the key characteristics typically associated with the 47LPA-150YR-R series: | Parameter | Value / Description | | :--- | :--- | | **Inductance** | 15 µH (Microhenries) | | **Tolerance** | ±20% (indicated by 'M') or ±30% | | **Mounting Type** | Surface Mount Device (SMD/SMT) | | **Current Rating (Isat)** | Typically 1.5A to 3.0A (varies by specific footprint) | | **DC Resistance (DCR)** | Low (optimized for high efficiency) | | **Shielding** | Shielded construction (minimizes EMI) | --- ### ## Component Identification The part number can be broken down to understand its properties: 1. **47LPA**: The series identifier. "LP" often stands for **Low Profile**, and "A" usually denotes an automotive or advanced grade. 2. **150**: The inductance code. The first two digits are significant figures, and the third is the multiplier ($15 \times 10^0 = 15$). 3. **Y/R**: Tolerance and packaging indicators (e.g., Tape & Reel). --- ### ## Typical Applications These inductors are found in circuits requiring stable power delivery in small form factors: * **DC-DC Converters:** Buck or boost converters for battery-powered devices. * **Mobile Electronics:** Smartphones, tablets, and wearable tech where height is a constraint. * **Automotive Infotainment:** Used in dash displays and sensors. * **LED Drivers:** Providing constant current for lighting modules. --- ### ## Internal Structure (Conceptual) The part is constructed using a wire-wound coil around a ferrite core, often molded with a metallic powder to reduce electromagnetic interference (EMI). ```yaml Construction: Core Material: Ferrite or Metal Composite Winding: Copper wire Termination: Lead-free (RoHS Compliant) Shielding: Magnetic shielding to prevent crosstalk ```
