Based on the part number provided, **AISC-Q0649-R11** refers to a high-performance, automotive-grade **shielded power inductor** manufactured by Abracon. --- ## Technical Specifications Overview The "AISC-Q" series is specifically designed for automotive applications requiring high reliability and performance under harsh conditions. Below are the primary technical characteristics: | Parameter | Value / Specification | | :--- | :--- | | **Component Type** | Shielded Power Inductor | | **Inductance** | 0.11 µH (indicated by "R11") | | **Tolerance** | ±20% (Standard for this series) | | **Operating Temperature** | -40°C to +125°C | | **Qualification** | AEC-Q200 Grade 1 (Automotive Standard) | | **Shielding** | Magnetic Shielding (minimizes EMI) | --- ## Key Features ### 1. Automotive Grade (AEC-Q200) This component has passed rigorous stress tests, including thermal shock, moisture resistance, and mechanical vibration, making it suitable for use in engine control units (ECUs) and advanced driver-assistance systems (ADAS). ### 2. Low DCR (DC Resistance) The R11 variant is designed with very low resistance to minimize power loss through heat, which maximizes the efficiency of the power supply circuit. ### 3. Magnetic Shielding The inductor is encapsulated in a magnetic material. This prevents electromagnetic interference (EMI) from leaking out and affecting sensitive nearby components, which is critical in dense PCB layouts. ### 4. High Saturation Current Because it has a low inductance value (0.11 µH), this part is typically capable of handling very high peak currents without the magnetic core "saturating" (losing its inductive properties). --- ## Typical Applications * **DC-DC Converters:** Used in point-of-load (POL) power supplies. * **Infotainment Systems:** Powering screens and processors in vehicles. * **LED Lighting:** Driving high-current LED arrays in automotive headlamps. * **Battery Management Systems (BMS):** Efficient energy conversion in EV/HEV systems. ---
