The **47LPQ-50R-R** is a specific part number typically associated with **Power Inductors** or **Fixed Inductors**, often used in automotive or industrial power supply applications. It is designed to handle high current loads while maintaining high stability. --- ### Technical Specifications & Characteristics Below are the typical specifications for this component: | Feature | Description | | :--- | :--- | | **Component Type** | Shielded Power Inductor | | **Inductance** | 50.0 µH (Microhenries) | | **Tolerance** | ±20% (Standard for L series) | | **Mounting Type** | Surface Mount (SMD) | | **Operating Temperature** | -40°C to +125°C (AEC-Q200 compliant models) | | **Material** | Ferrite Core | --- ### Key Features 1. **Magnetic Shielding**: The "LPQ" series usually features a shielded construction. This prevents electromagnetic interference (EMI) from affecting surrounding sensitive components on the PCB. 2. **High Saturation Current**: Designed to handle significant current peaks without the inductance dropping significantly (saturation). 3. **Low DCR (DC Resistance)**: Minimizes power loss as heat, making it efficient for DC-DC converters. 4. **AEC-Q200 Grade**: Many parts in this series are qualified for automotive use, meaning they can withstand high vibration and extreme temperature fluctuations. --- ### Application Use-Cases * **DC-DC Converters**: Used to store energy and filter noise in step-up (boost) or step-down (buck) regulators. * **LED Drivers**: Provides stable current for high-brightness LED arrays. * **Automotive Infotainment**: Power filtering for dashboard displays and audio systems. * **Industrial Power Supplies**: Used in noise suppression and smoothing output current. --- ### Part Number Breakdown (Typical) | Segment | Meaning | | :--- | :--- | | **47** | Series Identifier (Product dimensions/platform) | | **LPQ** | Low Profile / High Q Factor / Shielded | | **50R** | Inductance Value (50 µH) | | **-R** | RoHS Compliant (Lead-free) |
