The **M2AS1-5323-R** is a specific electronic component typically categorized as a **Surface Mount (SMD) Power Inductor** or a specialized magnetic component, often produced by manufacturers like *Coilmaster Electronics* or similar specialty inductor firms. Below is a detailed breakdown of its electronic characteristics and technical specifications. --- ## 1. Core Specifications Inductors of this series are designed for high-efficiency power conversion. The alphanumeric code typically breaks down as follows: | Parameter | Description | Typical Value/Range | | :--- | :--- | :--- | | **Inductance** | The amount of magnetic flux generated | 23 µH (indicated by the '23' suffix) | | **Tolerance** | Variance from the nominal inductance | ±20% (standard for power inductors) | | **Current Rating (Irms)** | Continuous DC current capacity | ~1.5A to 3.0A (varies by specific sub-series) | | **Saturation Current (Isat)** | Point where inductance drops | The current at which L drops by 30% | | **DC Resistance (DCR)** | Internal copper resistance | Low (mΩ range) to minimize heat loss | --- ## 2. Physical and Material Properties This part is designed for automated assembly and harsh electrical environments. * **Mounting Type:** SMD (Surface Mount Device). It features flat underside terminals for reflow soldering. * **Shielding:** Usually **Magnetic Shielded**. This prevents Electromagnetic Interference (EMI) from affecting nearby components on the PCB. * **Core Material:** Ferrite core. Ferrite offers high permeability and low eddy current losses, making it ideal for high-frequency switching. * **RoHS Compliance:** The "-R" suffix usually denotes **RoHS Compliant**, meaning it is free from lead and other hazardous substances. --- ## 3. Common Applications The M2AS1 series is primarily found in DC-DC conversion circuits where voltage needs to be stepped up or down. 1. **Buck/Boost Converters:** Used for energy storage during the switching cycle. 2. **Power Supplies:** Found in laptops, tablets, and LED drivers. 3. **Noise Filtering:** Acts as a low-pass filter to smooth out ripple current in power lines. 4. **Consumer Electronics:** Used in high-density boards where small footprints and low profiles are required. --- ## 4. Typical Footprint (Dimensions) While exact dimensions depend on the manufacturer's datasheet for the "5323" size code, it generally refers to the metric or imperial package size: * **Estimated Size:** Approximately 5.0mm x 5.0mm with a height of roughly 2.3mm to 3.0mm. ---
