The part number **47LCT-152B-R** typically refers to a **Power Inductor**, specifically a shielded surface-mount (SMD) component designed for power management circuits. Below is a detailed breakdown of its specifications and characteristics based on standard industry naming conventions for this series. --- ### 1. Technical Specifications | Parameter | Specification (Typical) | | :--- | :--- | | **Inductance** | 1.5 µH (Microhenries) | | **Tolerance** | ±20% (indicated by 'M' or 'B' in some series) | | **Component Type** | Shielded Power Inductor | | **Mounting Type** | Surface Mount (SMD/SMT) | | **Material Core** | Ferrite or Carbonyl Iron | | **Packaging** | Tape & Reel (indicated by '-R') | ### 2. Part Number Breakdown The nomenclature can be decoded as follows: * **47LCT**: The series designation (often associated with low-profile, high-current power inductors). * **152**: The inductance value code. The first two digits are significant figures, and the third is the multiplier. * $15 \times 10^2$ = 1500 nH = **1.5 µH**. * **B**: Tolerance or internal design revision code. * **-R**: Indicates **RoHS Compliant** and/or packaged in **Tape & Reel**. --- ### 3. Key Features * **Magnetic Shielding**: The "shielded" construction minimizes Electromagnetic Interference (EMI), preventing the magnetic field from affecting nearby components on the PCB. * **High Current Capability**: Designed to handle significant DC currents without saturating the core. * **Low DC Resistance (DCR)**: Optimized to reduce power loss (heat) during operation, improving overall energy efficiency. * **Compact Footprint**: Ideal for high-density circuit boards found in modern electronics. ### 4. Common Applications These inductors are primarily used in **DC-DC Converters** and voltage regulation modules. Specific applications include: 1. **Consumer Electronics**: Laptops, tablets, and smartphones. 2. **Power Supplies**: Point-of-Load (POL) converters. 3. **Communication**: Base stations and networking equipment. 4. **Automotive**: Infotainment systems and LED lighting drivers. ---
