## AISC-0805-R039 Electronic Component Overview The **AISC-0805-R039** is a Surface Mount (SMD) Wire-Wound Inductor manufactured by Abracon. It belongs to the AISC series, which is designed for high-frequency applications requiring high stability and precision. --- ### 1. Key Technical Specifications The part number itself acts as a code for its primary characteristics. Below are the specific parameters for this component: | Parameter | Value | Notes | | :--- | :--- | :--- | | **Inductance** | 39 nH | Nanohenries | | **Tolerance** | ±5% (J) | Standard precision | | **Case Size** | 0805 (2012 Metric) | 2.0mm x 1.25mm | | **DC Resistance (DCR)** | 0.15 Ω (Max) | Affects power efficiency | | **Rated Current** | 600 mA | Maximum continuous current | | **Self-Resonant Frequency** | 2000 MHz | Minimum SRF | | **Quality Factor (Q)** | 50 (Min) | Measured at 500 MHz | --- ### 2. Physical Construction The **AISC-0805** series uses a **wire-wound** construction over a ceramic core. * **Ceramic Core:** Provides excellent thermal stability and a high Self-Resonant Frequency (SRF), making it ideal for RF applications. * **Wire-Wound Design:** Unlike multilayer inductors, the wire-wound method allows for much higher Q-factors and lower DCR, which minimizes signal loss. * **Encapsulation:** Usually coated with a clear epoxy resin for mechanical protection during pick-and-place assembly. --- ### 3. Common Applications Due to its high Q-factor and high-frequency performance, this part is typically used in: * **RF Circuits:** Matching networks, filters, and oscillators. * **Wireless Communication:** Bluetooth, Wi-Fi, and cellular infrastructure. * **High-Speed Data:** Signal conditioning in high-frequency data lines. * **Tuned Circuits:** Where precise inductance values are required to maintain frequency stability. --- ### 4.
