Based on the part number **47LPQ-02YR-R**, this component belongs to the **47L Series** of miniature low-profile power inductors, typically manufactured by brands like **Gowanda Electronics** or specialized power magnetic suppliers. These are designed for high-efficiency power conversion in space-constrained environments. --- ## 🛑 Component Specifications The "47LPQ" designation indicates a **Low Profile, High Q** (Quality factor) inductor. Below is a breakdown of its technical characteristics: | Feature | Specification Details | | :--- | :--- | | **Component Type** | Power Inductor (Surface Mount) | | **Inductance** | 2.0 µH (Identified by "02" code) | | **Tolerance** | ±20% (Typical for the "R" suffix) | | **Construction** | Shielded or Semi-shielded core to reduce EMI | | **Operating Temp** | -40°C to +125°C (Industrial Grade) | | **Termination** | RoHS Compliant (Lead-Free) | --- ## 🛠 Key Features ### 1. Low Profile Design The "LP" in the prefix stands for **Low Profile**. These parts are engineered to have a very small height (often under 2.0mm or 3.0mm), making them ideal for: * Smartphone internals. * Wearable electronics. * Thin-profile laptops/tablets. ### 2. High Q Factor The "Q" suffix suggests a **High Quality Factor**. This means the inductor has low internal resistance (DCR), leading to: * Lower energy loss as heat. * Higher efficiency in DC-DC converters. * Better performance at high frequencies. ### 3. Magnetic Shielding Most parts in this series are shielded. This prevents the magnetic fields generated by the inductor from interfering with nearby sensitive components on the PCB, which is critical for dense circuit designs. --- ## 📡 Typical Applications The **47LPQ-02YR-R** is primarily used in the following circuits: 1. **DC-DC Converters:** Buck, Boost, or Buck-Boost regulators. 2. **Battery Management Systems (BMS):** Efficient power distribution in portable devices. 3. **Noise Filtering:** Removing high-frequency ripples from power supply lines. 4. **LED Drivers:** Providing steady current for backlighting or flash modules. --- ## 🔍 Part Number Breakdown (Logic) | Segment | Meaning | | :--- | :--- | | **47L** | Series Identifier (Low Profile Power Inductor) | | **PQ** | Performance Grade (High Q / Power) | | **02** | Inductance Value (2.0 µH) | | **YR** | Size/Packaging Code | | **-R** | RoHS Compliant / Tape & Reel Packaging |
