## AISC-0805-R082: Technical Overview The **AISC-0805-R082** is a surface-mount (SMD) wire-wound ceramic chip inductor. It belongs to the 0805 series, which is a standard industry size for passive components. These components are primarily used in high-frequency applications due to their high Q-factors and stable inductance. --- ### 1. Part Number Breakdown Understanding the nomenclature helps identify its core specifications: | Part Segment | Definition | Value | | :--- | :--- | :--- | | **AISC** | Series Name | Abracon Inductor Surface Ceramic | | **0805** | Case Size | 0.08 x 0.05 inches (2.0 x 1.25 mm) | | **R082** | Inductance Value | **82 nH** (Nanohenries) | --- ### 2. Key Technical Specifications Based on the standard datasheet for the AISC-0805 series, the "R082" variant typically exhibits the following characteristics: | Parameter | Value (Typical) | | :--- | :--- | | **Inductance** | 82 nH | | **Tolerance** | ±5% (J) or ±10% (K) | | **Q Factor (Min)** | 60 (@ 500 MHz) | | **Self-Resonant Frequency (SRF)** | 1500 MHz (Minimum) | | **DC Resistance (DCR)** | 0.22 $\Omega$ (Maximum) | | **Rated Current (Idc)** | 600 mA | | **Operating Temperature** | -40°C to +125°C | --- ### 3. Construction and Features * **Wire-Wound Technology:** Unlike multilayer inductors, these use a copper wire wound around a ceramic core. This results in much higher **Q (Quality) factors** and higher current handling capabilities. * **Ceramic Body:** The alumina ceramic body provides excellent mechanical strength and thermal stability. * **High Resonance:** The structure minimizes stray capacitance, allowing the part to function at very high frequencies (GHz range) before reaching self-resonance. --- ### 4. Common Applications Due to its high frequency performance, the AISC-0805-R082 is commonly found in: 1. **RF Tranceivers:** Matching circuits for Bluetooth, Wi-Fi, and Zigbee. 2. **Filter Networks:** Low-pass or high-pass filters in telecommunications. 3. **Mobile Devices:** Signal conditioning in smartphones and tablets. 4. **VCOs:** Voltage Controlled Oscillators requiring stable inductance.
