The **47LPQ-01B-R** is a specific part number typically associated with high-performance **Magnetic components**, specifically a **High-Current Power Inductor** or a **Planar Transformer** module. These components are designed for high-density power conversion applications. --- ### 1. Component Overview The "47LPQ" series is often manufactured by companies like **Pulse Electronics** or similar magnetic specialty firms. These parts are engineered to handle significant current while maintaining a low profile (LP stands for Low Profile). | Feature | Specification (Typical) | | :--- | :--- | | **Component Type** | Power Inductor / Planar Magnetic | | **Mounting Type** | Surface Mount (SMD) | | **Core Material** | Ferrite | | **Shielding** | Shielded (Low EMI) | | **RoHS Status** | Compliant (indicated by the "-R" suffix) | --- ### 2. Key Technical Characteristics #### A. Planar Technology Unlike traditional wire-wound inductors, the 47LPQ series often utilizes **planar construction**. This involves using flat copper traces or lead frames instead of round wire. * **Benefit:** Provides a much higher surface area for cooling and reduces "skin effect" losses at high frequencies. * **Result:** Extremely high efficiency in a small footprint. #### B. High Current Handling These parts are designed for "Point of Load" (POL) converters and VRMs (Voltage Regulator Modules). They can typically handle saturation currents ranging from **30A to over 100A**, depending on the specific winding configuration. #### C. Low Profile (LP) The "LPQ" designation indicates a "Low Profile" geometry. This is critical for modern blade servers and slim electronic devices where vertical space (Z-height) is restricted. --- ### 3. Applications The 47LPQ-01B-R is commonly found in the following environments: 1. **Data Centers:** DC-DC converters for servers and high-speed networking gear. 2. **Graphics Cards:** High-end GPU power delivery phases. 3. **Industrial Computing:** Embedded systems requiring stable power under heavy loads. 4. **Telecommunications:** Distributed power architectures. --- ### 4. Part Number Breakdown (Generic Interpretation) | Segment | Meaning | | :--- | :--- | | **47** | Series Identifier (Size/Footprint) | | **LPQ** | Low Profile Planar | | **01B** | Specific Electrical Value (Inductance/Turns Ratio) | | **-R** | RoHS Compliant / Lead-Free | --- ### 5. Installation Note When soldering the 47LPQ-01B-R, it is vital to follow the **Reflow Profile** provided by the manufacturer. Because of the high copper content (thermal mass) in these components, they can act as a heat sink during the soldering process, requiring precise temperature control to ensure a reliable joint.
