The **AISC-1008-R068** is a high-performance, surface-mount (SMD) wire-wound power inductor part of the AISC-1008 series. These components are primarily used for energy storage, filtering, and noise suppression in electronic circuits. ### 1. Key Technical Specifications The part number "R068" specifically identifies the inductance value. Below are the technical parameters for this specific component: | Parameter | Value / Specification | | :--- | :--- | | **Inductance** | 0.068 µH (68 nH) | | **Tolerance** | Usually ±5% (J) or ±10% (K) | | **Case Size** | 1008 (2.5 mm x 2.0 mm) | | **DC Resistance (DCR)** | Max ~0.15 - 0.25 Ω (Varies by brand) | | **Rated Current (Idc)** | Max ~600 mA - 1000 mA | | **Self-Resonant Frequency** | High (Typical > 1000 MHz) | | **Operating Temperature** | -40°C to +125°C | --- ### 2. Component Construction The AISC-1008 series utilizes a specific physical build to optimize performance: * **Wire-Wound Core:** Fine copper wire is wound around a ceramic or ferrite core. This provides higher Q-factors and lower DCR compared to multilayer inductors. * **Encapsulation:** Often coated with epoxy or a resin to protect the windings from physical damage and environmental moisture. * **Termination:** High-quality plating (usually Tin over Nickel) to ensure excellent solderability during the SMT process. --- ### 3. Typical Applications Because of its small footprint (1008 size) and relatively high current handling, it is used in: 1. **RF Circuits:** Impedance matching and resonance in high-frequency communication modules. 2. **DC-DC Converters:** Voltage regulation in handheld devices like smartphones or tablets. 3. **EMI Suppression:** Filtering out high-frequency noise in power supply lines. 4. **Signal Processing:** Used in oscillators and filter networks. --- ### 4. Part Number Breakdown While manufacturer prefixes (like Abracon) may vary slightly, the nomenclature usually follows this logic: ```text AISC - 1008 - R068 - [Tolerance] - [Packaging] | | | | | Series Size Value J=5% T=Tape & Reel (68nH) K=10% ``` ---
