The **AISC-0603-R036** is a surface-mount (SMD) wire-wound ceramic chip inductor. It is commonly used in high-frequency RF applications due to its high precision and excellent performance characteristics. Below is a detailed breakdown of its electronic specifications and characteristics. --- ### 1. General Specifications The part number follows a standard industry naming convention. Here is the breakdown: * **AISC**: Series name (Wire-wound Chip Inductor). * **0603**: Package size (0.06 x 0.03 inches or 1.6 x 0.8 mm). * **R036**: Inductance value (0.036 µH or 36 nH). ### 2. Technical Parameters | Parameter | Specification | | :--- | :--- | | **Inductance** | 36 nH | | **Tolerance** | Usually ±5% (J) or ±2% (G) | | **Quality Factor (Q min)** | 37 (at 250 MHz) | | **Self-Resonant Frequency (SRF)** | ~2500 MHz (2.5 GHz) | | **DC Resistance (DCR max)** | 0.27 Ω | | **Rated Current (max)** | 600 mA | | **Operating Temperature** | -40°C to +125°C | --- ### 3. Key Electronic Characteristics #### A. Wire-Wound Construction Unlike multilayer inductors, this part uses a fine wire wound around a ceramic core. This construction provides: * **Higher Q Factors:** Better efficiency in RF circuits. * **Higher Current Handling:** Can carry more current compared to multilayer versions of the same size. * **Lower DCR:** Reduces power loss and heat generation. #### B. Self-Resonant Frequency (SRF) The SRF is 2.5 GHz. In electronic design, this inductor must be operated well below this frequency to maintain its inductive properties. Near the SRF, the parasitic capacitance begins to dominate, and the component starts behaving like a capacitor. #### C. High Q (Quality) Factor A high Q factor indicates low energy loss. This makes the AISC-0603-R036 ideal for: * **LC Filters:** For sharper resonance and better selectivity. * **Impedance Matching:** Maximizing power transfer between RF stages. --- ### 4. Common Applications * **Mobile Communication:** Cell phones, GPS, and Wi-Fi modules. * **RF Circuits:** Transceivers, power amplifiers, and oscillators. * **High-Speed Data:** Filtering noise in high-speed digital lines. ---
