The **LPE-62-R** is a specific electronic component, typically categorized as a **Surface Mount (SMT) Power Inductor**. These parts are commonly used in power management circuits for filtering, energy storage, and noise suppression. Below is a detailed breakdown of its electronic characteristics and specifications. --- ### 1. General Specifications The LPE-62-R series is designed for high-density mounting and efficiency. | Feature | Specification (Typical) | | :--- | :--- | | **Component Type** | Power Inductor | | **Mounting Type** | Surface Mount Device (SMD/SMT) | | **Core Material** | Ferrite | | **Shielding** | Non-shielded or Semi-shielded (depending on variant) | | **Operating Temp** | -40°C to +125°C (standard range) | ### 2. Key Electrical Parameters While specific values (like Inductance) depend on the numeric suffix following the "62-R" (e.g., LPE-62-R-100), the general characteristics for the 62-R footprint are: * **Inductance Range:** Usually spans from **1.0 µH to 1000 µH**. * **DC Resistance (DCR):** Optimized to be as low as possible to minimize power loss and heat generation. * **Saturation Current ($I_{sat}$):** The point at which the inductance drops by a specified percentage (usually 10-30%). * **RMS Current ($I_{rms}$):** The continuous current the inductor can handle based on temperature rise (usually 40°C rise). ### 3. Physical Dimensions (62-R Series) The "62" in the part number often refers to the physical sizing of the package. * **Footprint:** Approximately **6.0mm x 6.0mm**. * **Height:** Approximately **2.5mm to 3.0mm** (The "R" often signifies a specific profile or RoHS compliance). --- ### 4. Applications in Electronics The LPE-62-R is found in various DC-DC conversion environments: 1. **Buck/Boost Converters:** Used to store energy during the switching cycle to provide a steady output voltage. 2. **Filtering:** Acts as a low-pass filter to remove high-frequency noise from power lines. 3. **Battery Powered Devices:** Due to its small SMT form factor, it is ideal for laptops, tablets, and handheld medical devices. 4. **LED Drivers:** Used to stabilize the current flowing through high-brightness LEDs. ### 5. Identification and Marking * **Marking:** Usually features a 3-digit code (e.g., "101" represents $10 \times 10^1 = 100 \text{µH}$). * **RoHS Compliance:** The "R" suffix in modern electronic nomenclature almost always indicates that the part is **RoHS Compliant** (Lead-free). ---
