The **LPD-32P1-R** is a specific electronic component, typically categorized as a **Surface Mount (SMT) Power Inductor** or a specialized passive filter component, often produced by manufacturers like Coilcraft (within their LPD series). These parts are known for their low profile and dual-winding configuration. --- ### 1. Technical Specifications Below is a breakdown of the typical electronic characteristics for this component series: | Parameter | Description | | :--- | :--- | | **Component Type** | Power Inductor / Coupled Inductor | | **Mounting Type** | Surface Mount (SMD/SMT) | | **Inductance** | Usually ranges from 1.0 µH to 100 µH (depending on the specific dash number) | | **Core Material** | Ferrite | | **Configuration** | Dual Winding (1:1 Ratio) | | **Shielding** | Magnetically Shielded | --- ### 2. Key Features * **Low Profile:** The "LPD" designation stands for **Low Profile Dual**, making it ideal for compact electronic assemblies where vertical space is limited (e.g., smartphones, wearables). * **Coupled Inductor Design:** Because it contains two windings, it can be used as a: * 1:1 Transformer * Common Mode Choke * SEPIC converter inductor * **Magnetic Shielding:** The ferrite construction ensures minimal Electromagnetic Interference (EMI) with surrounding components. * **High Efficiency:** Designed for low DCR (DC Resistance) to minimize power loss. --- ### 3. Common Applications The LPD-32P1-R is frequently utilized in power management circuits: 1. **DC-DC Converters:** Specifically in SEPIC (Single-Ended Primary-Inductor Converter) or Flyback topologies. 2. **Voltage Regulation:** Used in point-of-load (POL) modules for laptops and tablets. 3. **EMI Filtering:** Acting as a common mode choke to filter out high-frequency noise in signal lines. 4. **Battery Powered Devices:** Due to its small footprint and high efficiency. --- ### 4.
