Key Technical Specifications | Parameter | Value | Details | | :--- | :--- | :--- | | **Inductance** | 0.24 µH (240 nH) | Measured at 25 MHz | | **Tolerance** | ±5% (J) | Standard precision for RF circuits | | **Package Size** | 0603 (EIA) / 1608 (Metric) | 1.6mm x 0.8mm x 1.0mm | | **DC Resistance (Max)** | 0.92 Ω | Important for power efficiency | | **Rated Current (Max)** | 350 mA | Maximum continuous current | | **SRF (Min)** | 550 MHz | Self-Resonant Frequency | | **Quality Factor (Q)** | 28 (Min) | Measured at 100 MHz | --- ### 2. Physical Construction and Features * **Wire-Wound Technology:** Unlike multilayer inductors, this part uses a wire wound around a ceramic core. This construction allows for a much higher **Q-factor** and lower DC resistance. * **Ceramic Core:** Provides excellent thermal stability and high-frequency performance. * **Termination:** Features gold or tin-plated terminals for high-quality soldering and oxidation resistance. --- ### 3. Application Areas The AISC-0603F-R24 is typically found in: * **RF Transceivers:** Used in matching networks and filters for wireless communication. * **Mobile Devices:** Cell phones, GPS modules, and Bluetooth devices. * **Broadband Equipment:** High-speed internet hardware where signal integrity is paramount. * **EMI Suppression:** Filtering high-frequency noise in sensitive circuits. --- ### 4. Circuit Considerations When designing a PCB with this part, keep the following in mind: 1. **SRF Limit:** Ensure your operating frequency is well below the Self-Resonant Frequency (550 MHz) to avoid the inductor behaving like a capacitor. 2. **Current Derating:** If the ambient temperature is high, the maximum rated current (350 mA) should be derated according to the manufacturer's datasheet. 3. **Placement:** Because it is a wire-wound component, it may be sensitive to electromagnetic interference (EMI) from nearby high-power components. ---
