The part number **OA2AE8016-R100** typically identifies a high-reliability, surface-mount **Power Inductor** (often manufactured by companies like Cyntec or similar specialized magnetic component suppliers). Below is the technical breakdown of its electronic characteristics and construction. --- ### 1. Technical Specifications This component is designed for DC-DC conversion and high-efficiency power management. | Parameter | Specification (Typical) | | :--- | :--- | | **Component Type** | Molded Power Inductor | | **Inductance** | 0.16 µH (indicated by "R100" or suffix codes) | | **Tolerance** | ±20% | | **Current Rating (Isat)** | High Saturation Current (typically >30A) | | **DC Resistance (DCR)** | Ultra-low (often <1.0 mΩ) | | **Operating Temp** | -55°C to +125°C | | **Construction** | Metal Alloy Powder / Shielded | --- ### 2. Key Features * **Molded Construction:** The coil is embedded in a metal powder composite. This provides excellent magnetic shielding and minimizes audible noise (buzzing) caused by magnetostriction. * **High Saturation:** Unlike ferrite inductors, these parts exhibit a "soft saturation" curve, meaning they don't lose inductance abruptly when current increases. * **Low Profile:** The "8016" in the part number often refers to the physical footprint, roughly **8.0mm x 8.0mm** with a height of **1.6mm**. * **High Efficiency:** The use of flat wire or specialized alloy reduces the Skin Effect and DC losses, making it ideal for high-frequency switching. --- ### 3. Application Use-Cases These parts are commonly found in high-performance computing and mobile electronics: 1. **Voltage Regulator Modules (VRM):** Used in CPU/GPU power phases. 2. **DC-DC Converters:** Point-of-Load (POL) converters in laptops and tablets. 3. **Battery Management:** High-current charging circuits. 4. **Servers:** High-density power supplies requiring small footprints and low heat dissipation. --- ### 4. Part Number Breakdown (Generalized) | Prefix (OA2) | Series/Size (AE8016) | Value Code (R100) | | :--- | :--- | :--- | | Manufacturer/Series Code | 8.0mm x 8.0mm x 1.6mm | "R" represents the decimal (0.100 - 0.160 µH) | ---
