The part number **AISC-0603-R0036** refers to a high-frequency **Surface Mount Device (SMD) Inductor**, typically manufactured by Abracon. ### 1. General Specifications This component belongs to the wire-wound ceramic core category, designed for high-frequency RF applications where stability and a high Quality (Q) factor are essential. | Parameter | Specification | | :--- | :--- | | **Inductance** | 3.6 nH (Nanohenries) | | **Case Size (EIA)** | 0603 (0.06 x 0.03 inches / 1.6 x 0.8 mm) | | **Tolerance** | ±0.3 nH (Commonly signified by the "S" or "J" suffix variations) | | **Core Material** | Ceramic | | **Operating Temp** | -40°C to +125°C | --- ### 2. Technical Performance Characteristics High-frequency inductors like the AISC-0603 series are defined by their efficiency at specific frequencies. * **Self-Resonant Frequency (SRF):** Usually rated above 6000 MHz (6 GHz). This determines the maximum frequency at which the component acts as an inductor before becoming capacitive. * **DC Resistance (DCR):** Extremely low (typically < 0.066 Ω), which minimizes power loss and heat generation. * **Rated Current:** Can handle high DC currents (often up to 700mA) relative to its small footprint. * **Quality Factor (Q):** High Q values (typically > 16 at 250MHz) ensure low signal loss in RF circuits. --- ### 3. Part Number Breakdown The nomenclature follows a standard industry format: | Segment | Meaning | | :--- | :--- | | **AISC** | Abracon Inductor Surface Ceramic (Series) | | **0603** | Physical dimensions (1.6mm x 0.8mm) | | **R0036** | Inductance value code (R0036 = 0.0036 µH = 3.6 nH) | --- ### 4. Typical Applications Due to its small size and high-frequency stability, it is commonly found in: 1. **Wireless Communication:** Cell phones, Wi-Fi routers, and Bluetooth modules. 2. **Matching Networks:** Used for impedance matching in antenna circuits. 3. **Filter Circuits:** High-pass or band-pass filters in RF front-ends. 4. **Satellite Equipment:** GPS receivers and satellite radio. ---
