## Technical Specifications for AISC-0805-R068 The **AISC-0805-R068** is a Surface Mount (SMD) Wire-Wound Inductor, typically manufactured by Abracon. It is part of the AISC-0805 series, which is designed for high-frequency applications where precision and high Q-factors are required. ### 1. Part Number Breakdown The part number follows a specific nomenclature that describes its physical and electrical characteristics: | Code Segment | Meaning | Description | | :--- | :--- | :--- | | **AISC** | Series | Ceramic core wire-wound chip inductor | | **0805** | Case Size | 0805 Imperial (2012 Metric) | | **R068** | Inductance | **68 nH** (R denotes decimal, 068 = 0.068 µH) | | **-J** (Optional) | Tolerance | Typically ±5% (J) or ±10% (K) | --- ### 2. Electrical Characteristics The "R068" specifically defines the inductance at 68 nanohenries. Below are the typical electrical parameters for this specific component: | Parameter | Value | | :--- | :--- | | **Inductance** | 68 nH | | **Tolerance** | ±5% (Standard) | | **Self-Resonant Frequency (SRF)** | > 1700 MHz | | **Quality Factor (Q) Min** | 60 (at 500 MHz) | | **DC Resistance (DCR) Max** | 0.38 Ω | | **Rated Current (Max)** | 500 mA | --- ### 3. Physical & Material Composition * **Core Material:** Ceramic. Ceramic cores provide excellent stability and high SRF, making them ideal for RF applications. * **Construction:** Wire-wound. This involves winding a fine copper wire around the ceramic core, which allows for higher Q-factors and lower DCR compared to multilayer inductors. * **Termination:** Gold or Tin-plated terminals for reliable soldering. * **Dimensions:** 2.29mm x 1.73mm x 1.52mm (standard 0805 footprint). --- ### 4. Key Applications Because of its high SRF and Q-factor, the AISC-0805-R068 is used in: 1. **RF Circuits:** Matching networks and filters for wireless communication. 2. **Bluetooth/Wi-Fi Modules:** Signal conditioning and noise suppression. 3. **High-Speed Data Lines:** Maintaining signal integrity in telecommunications. 4. **VCOs:** Voltage-controlled oscillators in radio transmitters. --- ### 5. Soldering & Handling * **Mounting:** Compatible with standard SMT reflow soldering processes. * **Operating Temperature:** Typically rated from **-40°C to +125°C**. * **Moisture Sensitivity:** Usually MSL 1 (Unlimited shelf life at <30°C/85% RH).
