The **47LV-331W-R** is a specific part number typically associated with **Inductors**, specifically high-performance power inductors used in surface-mount technology (SMT). Below is a detailed breakdown of the technical specifications, component structure, and typical applications. --- ### 1. Technical Specifications Based on the standard nomenclature for this series, here are the estimated technical parameters: | Parameter | Specification (Typical) | | :--- | :--- | | **Inductance** | 330 µH (Indicated by '331') | | **Tolerance** | ±10% to ±20% (Series dependent) | | **Mounting Type** | Surface Mount Device (SMD/SMT) | | **Configuration** | Shielded or Unshielded Drum Core | | **Operating Temp** | -40°C to +125°C | | **DC Resistance (DCR)** | Relatively low for high efficiency | ### 2. Part Number Breakdown Understanding the alphanumeric code helps in identifying the physical and electrical characteristics: * **47LV**: Usually refers to the series name or the physical dimensions (Case size). * **331**: The Inductance Value. * The first two digits (**33**) are the significant figures. * The third digit (**1**) is the multiplier ($10^1$). * Calculated: $33 \times 10 = 330$ µH. * **W/R**: These suffixes usually denote the packaging type (e.g., Tape and Reel) or environmental compliance (e.g., RoHS compliant). --- ### 3. Functional Role in Electronics This component is primarily used for energy storage and signal filtering. Its main functions include: 1. **DC-DC Conversion:** Acting as an energy storage element in buck or boost converters to provide steady output voltage. 2. **Noise Filtering:** Blocking high-frequency alternating current (AC) while allowing direct current (DC) to pass, effectively cleaning power lines. 3. **EMI Suppression:** Reducing electromagnetic interference in sensitive communication circuits. --- ### 4. Typical Applications * **Consumer Electronics:** Power supplies for LED TVs, laptops, and gaming consoles. * **Telecommunications:** Base station power modules and networking hardware. * **Industrial:** DC-DC converters and motor control circuits. * **Automotive:** Infotainment systems and dashboard electronics (if AEC-Q200 qualified). ---
