Based on the part number provided, **AISC-Q0656-R22** refers to a high-current, automotive-grade power inductor manufactured by **Abracon**. Below is a detailed breakdown of its electronic specifications and characteristics. --- ## 1. Specifications Overview The AISC-Q series is designed for high-performance power conversion in harsh environments. | Parameter | Value / Description | | :--- | :--- | | **Inductance** | 0.22 µH (indicated by "R22") | | **Tolerance** | ±20% (Standard for this series) | | **DCR (Direct Current Resistance)** | Very low (typically < 1.0 mΩ for R22) | | **Saturation Current ($I_{sat}$)** | High (typically 30A - 60A depending on case size) | | **Operating Temperature** | -55°C to +155°C | | **Qualification** | AEC-Q200 Grade 0 (Automotive) | --- ## 2. Part Number Breakdown Understanding the nomenclature helps identify the physical and electrical constraints: * **AISC-Q**: The series prefix, denoting Automotive Grade, High Current Inductors. * **0656**: The physical dimensions (Footprint). * **Length/Width**: Approx. 6.6 mm x 7.3 mm. * **Height**: Approx. 5.6 mm. * **R22**: The Inductance value. * **R** acts as a decimal point. * **22** = 0.22 microhenries (µH). --- ## 3. Key Electronic Features ### High Current Handling Due to the low DCR and specialized core material (usually metal alloy powder), these parts can handle high peak currents without entering magnetic saturation quickly. This is critical for high-efficiency Voltage Regulator Modules (VRMs). ### EMI Performance The part features a **shielded construction**. The magnetic flux is contained within the inductor body, minimizing Electromagnetic Interference (EMI) with neighboring sensitive circuits. ### Automotive Reliability * **AEC-Q200 Qualified**: Tested for mechanical shock, vibration, and thermal cycling. * **Lead-Free / RoHS Compliant**: Uses matte tin over copper plating. --- ## 4. Typical Applications Because of the low inductance (0.22 µH) and high current rating, this part is typically used in: 1. **DC-DC Converters**: Specifically Point-of-Load (PoL) converters for high-speed processors. 2. **Infotainment Systems**: Stable power delivery for automotive displays and CPUs. 3. **ADAS**: Powering sensors and camera modules where space is tight and heat is high. 4. **Battery Management Systems (BMS)**: Filtering and power regulation.
