The **LPE-5E-R** is a specific electronic component, typically categorized as a **Surface Mount (SMD) Power Inductor**. These parts are essential in power management circuits for regulating current and filtering noise. --- ### 1. Key Technical Specifications Below are the typical technical parameters for the LPE-5E-R series: | Parameter | Description | | :--- | :--- | | **Component Type** | Power Inductor (SMD) | | **Inductance Range** | Usually varies (e.g., 1.0µH to 1000µH depending on suffix) | | **Tolerance** | Typically ±20% (M) | | **Mounting Type** | Surface Mount Device (SMD/SMT) | | **Material Core** | Ferrite | | **Operating Temp** | -40°C to +125°C (Standard Industrial Grade) | --- ### 2. Core Functions The LPE-5E-R serves three primary roles in an electronic circuit: 1. **Energy Storage:** In DC-DC converters (like Buck or Boost converters), the inductor stores energy in its magnetic field when current flows through it. 2. **Noise Filtration:** It acts as a low-pass filter, blocking high-frequency AC noise while allowing stable DC current to pass through. 3. **Current Regulation:** It resists sudden changes in electric current, helping to stabilize the output voltage in power supply units. --- ### 3. Physical Characteristics * **Shielding:** Most "LPE" series inductors are **magnetically shielded**. This prevents the magnetic field generated by the inductor from interfering with nearby sensitive components (EMI - Electromagnetic Interference). * **Form Factor:** Designed for automated "Pick and Place" assembly. The "R" in the suffix often denotes **RoHS Compliance** (Lead-free) or **Taped and Reeled** packaging for manufacturing. --- ### 4. Common Applications The LPE-5E-R is frequently found in: * **Consumer Electronics:** Laptops, tablets, and smartphones. * **Power Supplies:** Switching Mode Power Supplies (SMPS). * **Communication Gear:** Base stations and networking routers. * **LED Drivers:** Circuits that require stable current to power high-brightness LEDs. --- ### 5. Identification Example If you are looking at the part number structure: `LPE` (Series Name) - `5E` (Case Size/Dimensions) - `R` (RoHS/Packaging)
