General Specifications Below are the primary technical parameters for this specific part number: | Parameter | Specification | | :--- | :--- | | **Inductance** | 0.47 µH (470 nH) | | **Tolerance** | ±30% (N) | | **Package Size (Metric)** | 2512 (2.5mm x 1.2mm) | | **Package Size (Imperial)** | 1005 | | **Operating Temperature** | -55°C to +125°C | | **Mounting Type** | Surface Mount (SMD) | --- ### 2. Part Number Breakdown Understanding the nomenclature helps identify the physical and electrical characteristics of the component: * **SDCL**: Series Code (Multilayer Chip Inductor for high frequency). * **1V**: Voltage/Internal Designator (specific to the manufacturer's process). * **2512**: Dimensions (Length 2.5mm x Width 1.2mm). * **R47**: Inductance Value. "R" acts as the decimal point (0.47 µH). * **N**: Tolerance (±30%). * **R**: Packaging Style (usually refers to Tape & Reel). --- ### 3. Key Characteristics * **Multilayer Structure:** Unlike wire-wound inductors, these are constructed by layering ceramic materials and screen-printing conductive patterns. This results in high reliability and a compact form factor. * **High Self-Resonant Frequency (SRF):** Designed for high-frequency applications where the inductor needs to maintain its inductive properties without turning capacitive. * **Magnetic Shielding:** The multilayer construction provides a degree of self-shielding, reducing electromagnetic interference (EMI) with neighboring components. --- ### 4. Typical Applications These inductors are commonly found in: 1. **Mobile Communication:** Cell phones, GPS modules, and Bluetooth devices. 2. **High-Speed Signal Lines:** Filtering noise in digital circuits. 3. **WLAN/Wi-Fi Modules:** Matching circuits and resonance circuits in wireless networking hardware.
