### Overview of the 1008C-R82 The **1008C-R82** is a specific surface-mount technology (SMT) electronic component, primarily categorized as a **Wirewound Chip Inductor**. It is widely used in high-frequency applications due to its high Quality (Q) factor and stability. --- ### Technical Specifications Below is a breakdown of the core technical parameters for the "R82" variant within the 1008C series: | Parameter | Specification | | :--- | :--- | | **Component Type** | Fixed Inductor (Wirewound) | | **Inductance** | 0.82 µH (820 nH) | | **Case Code** | 1008 (2520 Metric) | | **Dimensions** | 2.5 mm x 2.0 mm | | **Tolerance** | Typically ±5% (J) or ±10% (K) | | **Material Core** | Ceramic | | **SRF (Self-Resonant Frequency)** | ~250 MHz to 350 MHz | | **Current Rating (DC)** | ~400 mA to 650 mA (varies by manufacturer) | --- ### Part Number Breakdown The nomenclature follows a standard industry format: 1. **1008**: Represents the physical size of the package. It measures **0.10 inches by 0.08 inches**. 2. **C**: Usually denotes a **Ceramic** core. Ceramic cores are preferred for high-frequency RF applications because they provide excellent thermal stability and high Q. 3. **R82**: The inductance value. The "R" acts as a decimal point. * **R82** = 0.82 Microhenries (µH). --- ### Key Applications Due to its construction, the 1008C-R82 is optimized for RF (Radio Frequency) circuitry: * **RF Tuning & Matching:** Used in wireless communication devices to match impedance between antennas and amplifiers. * **Filters:** Integrated into low-pass or band-pass filters to block unwanted frequencies. * **Oscillators:** Provides stable inductance for frequency generation. * **Decoupling:** Used in power lines to suppress high-frequency noise. --- ### Construction and Performance * **Wirewound Design:** Unlike multilayer inductors, these use a wire coiled around a ceramic body. This results in significantly higher current handling and a higher **Q factor**, meaning lower energy loss. * **Ceramic Core:** Provides no magnetic permeability (unlike ferrite), making it ideal for very high-frequency signals where ferrite losses would be too great.
