## Electronic Specifications for AISC-Q0603HQ-R30 The **AISC-Q0603HQ-R30** is a high-frequency, high-Q wire-wound chip inductor manufactured by Abracon. It is specifically designed for automotive and telecommunications applications where low loss and high stability are critical. ### 1. Key Technical Specifications The part number follows a specific nomenclature. Here is the breakdown of its primary electronic characteristics: | Parameter | Value | Details | | :--- | :--- | :--- | | **Inductance** | 300 nH (0.3 µH) | Measured at a specific test frequency. | | **Tolerance** | ±5% (J) | Standard tolerance for this series. | | **Case Size** | 0603 (EIA) / 1608 (Metric) | 1.6mm x 0.8mm footprint. | | **Q-Factor (Min)** | 35 | High Quality factor for low signal loss. | | **Self-Resonant Frequency (SRF)** | 850 MHz (Min) | The frequency at which it stops acting as an inductor. | | **DC Resistance (DCR)** | 1.10 Ω (Max) | Resistance of the wire winding. | | **Rated Current** | 200 mA (Max) | The maximum continuous current the part can handle. | --- ### 2. Internal Construction and Materials The "HQ" designation refers to the **High Q** nature of the component, which is achieved through specific construction methods: * **Wire-Wound Technology:** Unlike multilayer inductors, this uses a copper wire wound around a ceramic core. This results in much higher Q-factors and higher current handling. * **Ceramic Core:** Provides excellent thermal stability and very low dielectric loss, making it ideal for RF (Radio Frequency) circuits. * **AEC-Q200 Qualified:** The "Q" in the prefix indicates it is qualified for automotive environments, meaning it can withstand high vibration and wide temperature swings. --- ### 3. Application Use Cases Due to its high frequency resonance and low DCR, this part is typically used in the following circuits: 1. **RF Matching Networks:** Tuning antennas for Bluetooth, Wi-Fi, or LTE. 2. **Frequency Filters:** Used in Band-pass or Low-pass filters to remove noise. 3. **VCOs (Voltage Controlled Oscillators):** Stabilizing high-frequency oscillators. 4. **Automotive Telematics:** GPS modules and eCall systems where AEC-Q200 reliability is required. --- ### 4. Part Number Breakdown `AISC` - `Q` - `0603` - `HQ` - `R30` * **AISC:** Abracon Inductor Series Chip. * **Q:** AEC-Q200 Automotive Grade. * **0603:** Package Size (0.06 x 0.03 inches). * **HQ:** High Q-Factor Series. * **R30:** Inductance value (R represents the decimal; R30 = 0.30 µH or 300 nH).
