The **1008F-R24K** is a specific part number for a **Surface Mount (SMD) Wire-wound Chip Inductor**. These components are widely used in radio frequency (RF) circuits for filtering, impedance matching, and resonance. --- ### 1. Technical Specifications The part number follows a standardized naming convention. Here is the breakdown of its technical parameters: | Parameter | Value | Description | | :--- | :--- | :--- | | **Case Size** | 1008 (2520 Metric) | Dimensions: 0.10 x 0.08 inches (2.5 x 2.0 mm). | | **Inductance** | 0.24 µH (240 nH) | The "R24" denotes 0.24. | | **Tolerance** | ±10% | Indicated by the "K" suffix. | | **Core Material** | Ferrite / Ceramic | High-frequency performance material. | | **Mounting Type** | SMD/SMT | Designed for automated pick-and-place assembly. | --- ### 2. Component Breakdown The 1008F-R24K belongs to the "Wire-wound" family. Unlike multilayer inductors, wire-wound versions consist of a copper wire wrapped around a core. * **High Q Factor:** Because it uses actual wire, it has lower DC resistance (DCR) and a higher Quality (Q) factor compared to multilayer types, making it efficient for RF signals. * **SRF (Self-Resonant Frequency):** This component is designed to operate effectively up to a specific frequency limit before it starts behaving like a capacitor. * **Current Rating:** It is rated for a specific maximum DC current (typically in the range of 200mA to 600mA depending on the specific manufacturer like Coilcraft or Gowanda). --- ### 3. Common Applications Due to its size and inductance value (240 nH), this part is commonly found in: 1. **Mobile Communications:** Signal tuning in smartphones and tablets. 2. **RF Filters:** Band-pass or Low-pass filters in wireless transmitters. 3. **Impedance Matching:** Ensuring maximum power transfer between an antenna and a transceiver. 4. **Broadband Hardware:** Cable modems and high-speed routers. --- ### 4. Part Number Decoding If you are looking at different variations, here is how to read the code: * **1008**: The physical footprint (Length x Width). * **F**: Often denotes the series or core type (e.g., Ferrite). * **R24**: The value. "R" acts as a decimal point. $R24 = 0.24 \mu H$. * **K**: Tolerance code. ($J = 5\%$, $K = 10\%$, $M = 20\%$).
