The **OA2AE2716-R100** is a specific part number typically associated with high-current, surface-mount power inductors, often used in automotive and industrial power management applications. --- ### 1. Technical Specifications Overview Inductors like the R100 series are designed for high-frequency DC-DC converters where efficiency and high saturation currents are critical. | Parameter | Typical Value | Notes | | :--- | :--- | :--- | | **Inductance** | 0.10 µH (100nH) | Indicated by the "R100" suffix | | **Tolerance** | ±20% | Standard for power inductors | | **Mounting Type** | SMD/SMT | Surface Mount Technology | | **Core Material** | Composite/Metal Alloy | High saturation, low acoustic noise | | **Shielding** | Shielded | Minimizes EMI (Electromagnetic Interference) | --- ### 2. Key Features * **High Current Handling:** Designed to handle high ripple currents without reaching magnetic saturation. * **Low DCR (DC Resistance):** Uses flat wire or optimized copper windings to minimize power loss and heat generation. * **Thermal Stability:** Often rated for automotive grade temperatures (e.g., -40°C to +125°C or +155°C). * **Soft Saturation:** Unlike ferrite cores that drop inductance sharply, metal alloy cores provide a gradual drop in inductance as current increases. --- ### 3. Application Areas These components are integral to modern electronic power phases: 1. **Voltage Regulator Modules (VRM):** Used in CPU/GPU power delivery. 2. **Automotive Electronics:** Infotainment systems, ADAS, and LED lighting drivers. 3. **DC-DC Converters:** Buck, Boost, and Buck-Boost topologies for battery-powered devices. 4. **Point of Load (POL):** Distributed power systems requiring small footprints. --- ### 4. Part Number Breakdown (Generic) While manufacturers vary slightly, the nomenclature usually follows this logic: * **OA2AE:** Series/Family code (often indicates size and material). * **2716:** Physical dimensions (e.g., 2.7mm x 1.6mm or similar footprint). * **R100:** Inductance value where "R" acts as a decimal point ($0.100\mu H$). ---
