The **CTLL1608J-R10J** is a surface-mount electronic component, specifically a **multilayer ceramic chip inductor**. This part is commonly used in high-frequency circuits for signal filtering and impedance matching. Below is a detailed breakdown of its technical specifications and characteristics. --- ### 1. Part Number Breakdown The part number follows a standard nomenclature used by manufacturers (like Central Technologies): | Segment | Meaning | Description | | :--- | :--- | :--- | | **CTLL** | Series | Multilayer Chip Inductor Series | | **1608** | Case Size | 1.6mm x 0.8mm (EIA 0603 Package) | | **J** | Material | Specific ceramic material type for high frequency | | **R10** | Inductance | **0.10 µH** (or 100 nH) | | **J** | Tolerance | **±5%** | --- ### 2. Technical Specifications These values are typical for this specific component: * **Inductance:** 100 nH (0.10 µH) * **Tolerance:** ±5% * **Case Size:** 0603 (Inch) / 1608 (Metric) * **Quality Factor (Q):** Typically high (e.g., 15-20 minimum at specific frequencies) to minimize energy loss. * **Self-Resonant Frequency (SRF):** Usually in the range of 300MHz to 600MHz (depending on the exact manufacturer datasheet). * **DC Resistance (DCR):** Relatively low, typically around 0.50 to 1.0 Ohms. * **Rated Current:** Generally between 100mA and 300mA. --- ### 3. Key Features & Construction 1. **Multilayer Structure:** Unlike wire-wound inductors, this is built by layering ceramic material and conductive paste. This makes it very small and physically robust. 2. **Magnetic Shielding:** The multilayer design provides a closed magnetic circuit, resulting in low crosstalk/interference with surrounding components. 3. **High-Frequency Performance:** Excellent for applications above 100MHz due to its high SRF. --- ### 4. Common Applications * **Mobile Devices:** Cellular phones, Bluetooth modules, and WLAN cards. * **RF Modules:** Impedance matching in radio frequency amplifiers. * **Filtering:** Low-pass or band-pass filters in high-speed signal lines. * **Decoupling:** Eliminating high-frequency noise in power supply lines for sensitive ICs. ---
