The **AISC-0805-R015** is a specific type of **Surface Mount (SMD) Wire-Wound Ceramic Chip Inductor**. It is part of the AISC-0805 series manufactured by Abracon (and other compatible manufacturers). Below is a detailed breakdown of its electronic characteristics and technical specifications. --- ## 1. Part Number Breakdown Understanding the nomenclature helps identify the component's physical and electrical limits: | Part Segment | Meaning | Detail | | :--- | :--- | :--- | | **AISC** | Series Code | High-Frequency Wire-Wound Inductor | | **0805** | Case Size | 2.0mm x 1.25mm (Imperial 0805) | | **R015** | Inductance Value | **15 nH** (Nanohenries) | --- ## 2. Technical Specifications The "R015" variant is designed for high-frequency performance. Here are the typical electrical parameters for this specific value: ### Electrical Profile * **Inductance:** 15 nH * **Tolerance:** Typically $\pm$5% (J) or $\pm$10% (K) * **Quality Factor (Q min):** ~50 at 500MHz (Indicates high efficiency/low loss) * **Self-Resonant Frequency (SRF):** >4000 MHz (4.0 GHz) * **DC Resistance (DCR max):** ~0.17 $\Omega$ * **Rated Current (Imax):** ~600 mA ### Physical Construction * **Core Material:** Ceramic (Non-magnetic). This allows for high SRF and excellent stability. * **Winding:** Precision wire-wound construction for higher Q-factors compared to multilayer types. * **Termination:** Gold-plated or Tin-plated (lead-free) for SMD soldering. --- ## 3. Key Applications Because of its ceramic core and wire-wound design, this part is ideal for RF (Radio Frequency) circuits where signal integrity is critical. 1. **RF Matching Networks:** Tuning antennas in Wi-Fi or Bluetooth modules. 2. **Filter Circuits:** Used in Band-pass or High-pass filters. 3. **VCOs:** Voltage Controlled Oscillators requiring stable inductance. 4. **Telecommunications:** High-speed data transmission equipment. --- ## 4. Comparison: Ceramic vs. Ferrite Core It is important to note why the **AISC-0805** uses a ceramic core: | Feature | Ceramic Core (AISC) | Ferrite Core | | :--- | :--- | :--- | | **Inductance Range** | Low (nH range) | High ($\mu$H range) | | **Frequency** | Very High (GHz) | Lower (MHz) | | **Saturation** | Does not saturate | Subject to magnetic saturation | | **Purpose** | RF / Signal Integrity | Power Filtering / Storage | ---
