The **1008F-R24F** is a specific part number for a **Surface Mount (SMT) Inductor**, commonly used in radio frequency (RF) and signal processing applications. This component belongs to the "Wire-wound" family of ceramic core inductors. --- ### ## Technical Specifications Below are the primary electrical and physical characteristics of the 1008F-R24F: | Parameter | Value | Details | | :--- | :--- | :--- | | **Inductance** | 240 nH (0.24 µH) | The primary inductance value. | | **Tolerance** | ±1% (F) | High precision (F-suffix denotes 1%). | | **Package Size** | 1008 (EIA) | 2.5 mm x 2.0 mm footprint. | | **Core Material** | Ceramic | High-frequency performance stability. | | **Max DC Current** | ~500 - 650 mA | Depends on temperature rise (typical for this class). | | **Quality Factor (Q)** | 45 (Min) | Measured at specific frequencies (usually 100MHz). | | **SRF (Self Resonant Freq)** | ~550 MHz | Minimum frequency where it acts as an inductor. | --- ### ### Part Number Breakdown The naming convention follows a standard industry format, usually associated with manufacturers like **Fastron** or **Coilcraft**: 1. **1008**: Refers to the physical dimensions (0.10 inches by 0.08 inches). 2. **F**: Often signifies the series (Ferrite/Frequency) or construction type. 3. **R24**: The inductance value. "R" acts as the decimal point (R24 = 0.24 µH = 240 nH). 4. **F**: The tolerance code (F = ±1%, G = ±2%, J = ±5%). --- ### ### Key Features & Applications #### Features: * **High Q Factor:** Offers low loss at high frequencies, making it ideal for filters. * **Wire-wound Construction:** Provides much higher current handling and lower DC resistance compared to multilayer inductors. * **Tight Tolerance:** The 1% tolerance makes it suitable for precision tuning circuits. #### Typical Applications: * **RF Transceivers:** Used in the matching networks of wireless communication devices. * **Filters:** Band-pass or low-pass filters in telecommunications. * **Impedance Matching:** Ensuring maximum power transfer between stages in an RF circuit. * **Mobile Electronics:** Bluetooth, Wi-Fi, and GPS modules. --- ### ### Soldering & Footprint Code ```c // Example Footprint Dimensions (1008 Metric 2520) Length: 2.50 mm (+/- 0.2) Width: 2.00 mm (+/- 0.2) Height: 1.60 mm (+/- 0.2) ```
