The **AISC-0805-R0068** is a surface-mount (SMD) power inductor. It belongs to the **AISC-0805** series, which is characterized by a ceramic core and high-frequency performance, typically manufactured by companies like Abracon. --- ### 1. Part Number Breakdown Understanding the alphanumeric code helps identify the component's specifications: | Code Segment | Meaning | Description | | :--- | :--- | :--- | | **AISC** | Series Name | High Frequency Ceramic Chip Inductor | | **0805** | Case Size | Dimensions (0.08 x 0.05 inches / 2.0 x 1.25 mm) | | **R** | Decimal Point | Indicates the value is in Microhenries ($\mu H$) | | **0068** | Inductance Value | $0.0068 \mu H$ or **6.8 nH** | --- ### 2. Key Technical Specifications Based on standard datasheets for the 0805 series at this inductance level: * **Inductance:** 6.8 nH (Nanohenries). * **Tolerance:** Usually $\pm 5\%$ (J) or $\pm 10\%$ (K). * **Quality Factor (Q):** Typically high (approx. 40-60 at 500MHz), making it suitable for RF applications. * **Self-Resonant Frequency (SRF):** Very high, usually above 4000 MHz (4 GHz). * **Rated Current ($I_{dc}$):** Usually around 500mA to 800mA. * **DC Resistance (DCR):** Low, typically < 0.15 $\Omega$. --- ### 3. Construction and Material * **Core Material:** Ceramic. Unlike ferrite cores, ceramic cores do not saturate and provide excellent stability across a wide temperature range. * **Termination:** Typically tin (Sn) over nickel (Ni) barrier, suitable for reflow soldering. * **Operating Temperature:** Generally rated for $-40^\circ C$ to $+125^\circ C$. --- ### 4. Typical Applications Due to its low inductance and high resonant frequency, this part is used in: 1. **RF Circuits:** Matching networks, filters, and oscillators. 2. **Wireless Communication:** WiFi, Bluetooth, and cellular base stations. 3. **High-Speed Signal Lines:** To suppress EMI (Electromagnetic Interference) without degrading signal integrity. ---
