The term **28362** usually refers to a specific electronic component category, most commonly associated with **Surface Mount Device (SMD) Power Inductors** or specific **Power Management Modules**. Below is a breakdown of the parts typically associated with this part number. --- ## 1. Primary Identification: Power Inductors In the electronics industry, **28362** is frequently used as a shorthand for the physical dimensions or a specific series of high-current inductors (often produced by brands like Vishay, Bourns, or generic OEM manufacturers). ### Technical Specifications | Feature | Typical Specification | | :--- | :--- | | **Component Type** | Shielded SMD Power Inductor | | **Inductance Range** | 0.10 µH to 100 µH | | **Current Rating** | 2A to 50A (depending on inductance) | | **Operating Temp** | -40°C to +125°C | | **Core Material** | Ferrite or Iron Powder | --- ## 2. LM28362 (Voltage Regulator) There is also a common association with the **LM28362** (often abbreviated as 28362 in internal databases). This is a specialized integrated circuit (IC). ### Key Features of LM28362 * **Function:** Dual High-Frequency Step-Down (Buck) DC-DC Converter. * **Input Voltage:** Usually 3V to 18V. * **Output Current:** Capable of delivering up to 3A per channel. * **Switching Frequency:** High frequency (up to 2MHz), which allows for very small external inductors and capacitors. * **Applications:** * DSP and FPGA power supplies. * Set-top boxes. * LCD displays. --- ## 3. Physical Footprint and Design If you are looking at a PCB layout, "2836" or "28362" may refer to the **Metric Case Size**. * **Metric 2836:** This indicates the component is approximately **2.8mm x 3.6mm**. * **Termination:** These parts are almost always **SMD (Surface Mount Device)**, designed to be soldered directly onto the surface of a PCB using a reflow oven. --- ## Summary Checklist When ordering or replacing a "28362" part, verify the following: 1. **Is it an Inductor?** Check for a "uH" (microhenry) value on the casing. 2. **Is it an IC?** Check if it has multiple pins (usually 10-20 pins) and is used for power regulation. 3. **Tolerance:** Ensure the replacement part matches the original tolerance (usually ±20%).
