The **1008F-R10F** is a specific part number for a **Surface Mount (SMD) Wire-wound Inductor**. These components are essential in radio frequency (RF) and signal processing circuits. Below is a detailed breakdown of its specifications and characteristics. ### 1. Part Number Breakdown The nomenclature usually follows industry-standard labeling (commonly used by manufacturers like Fastron or Delevan): | Segment | Identification | Meaning | | :--- | :--- | :--- | | **1008** | Case Size | Dimensions (Length x Width) are approx. 0.10 x 0.08 inches. | | **F** | Core Material | Often signifies a Ferrite core (high permeability). | | **R10** | Inductance Value | "R" acts as a decimal point. 0.10 µH (or 100 nH). | | **F** | Tolerance | Indicates a tolerance of ±1%. | --- ### 2. Technical Specifications While exact ratings can vary slightly by manufacturer, the 1008F-R10F typically adheres to these parameters: | Parameter | Value | | :--- | :--- | | **Inductance** | 0.10 µH (100 nH) | | **Tolerance** | ±1% (High Precision) | | **Core Material** | Ferrite | | **SRF (Self-Resonant Frequency)** | Typically > 400 MHz - 700 MHz | | **DC Resistance (DCR)** | Low (usually < 0.50 Ω) | | **Rated Current** | Generally 200mA to 600mA (application dependent) | --- ### 3. Key Features * **High Precision:** The "F" suffix (1% tolerance) makes this part ideal for tuning circuits where exact frequency response is critical. * **Wire-wound Construction:** Unlike multilayer inductors, the wire-wound design provides a higher **Quality Factor (Q)** and lower DC resistance. * **Ferrite Core:** The use of ferrite allows for higher inductance values in a small footprint and better magnetic flux management compared to ceramic cores. --- ### 4. Common Applications Due to its high Q-factor and precise tolerance, this part is frequently found in: * **RF Transceivers:** Used in matching networks and filters for wireless communication. * **Oscillators:** Stability in frequency generation. * **EMI Filtering:** Suppressing high-frequency noise in power lines or signal paths. * **Mobile Communication:** Integrated into GPS, Wi-Fi, and Bluetooth modules. --- ### 5. Footprint (1008 Metric) The physical size is roughly **2.5mm x 2.0mm**. If you are designing a PCB (Printed Circuit Board), ensure your land pattern accounts for the side-termination electrodes common in wire-wound SMD components. ---
