The part number **1008F-R68K** refers to a specific type of surface-mount electronic component, specifically a **Wirewound Chip Inductor**. --- ## 1. Part Number Breakdown To understand the specifications, we can decode the alphanumeric string based on industry standards for inductors: | Segment | Meaning | Detail | | :--- | :--- | :--- | | **1008** | **Package Size** | Dimensions in inches (approx. 2.5mm x 2.0mm). | | **F** | **Series/Type** | Ferrite core (typically used for higher inductance/current). | | **R68** | **Inductance Value** | **0.68 µH** (Microhenries). | | **K** | **Tolerance** | **±10%** variation from nominal value. | --- ## 2. Technical Specifications While exact specifications can vary slightly between manufacturers (like Gowanda, API Delevan, or Coilcraft), the standard characteristics for a 1008F-R68K are: ### Electrical Properties * **Inductance:** 0.68 µH. * **Tolerance:** ±10%. * **Core Material:** Ferrite (provides a high Q factor and high SRF). * **Self-Resonant Frequency (SRF):** Usually in the range of 100 MHz to 500 MHz. * **DC Resistance (DCR):** Low resistance to minimize power loss. * **Current Rating:** Capable of handling moderate DC current (typically 300mA to 800mA depending on the specific series). --- ## 3. Physical Construction The **1008F** is a "Wirewound" inductor, meaning it consists of: 1. **Core:** A ceramic or ferrite rectangular block. 2. **Wire:** Fine copper wire wrapped around the core. 3. **Terminations:** Metallic end caps (usually Tin over Nickel) for soldering to a PCB. 4. **Encapsulation:** Often coated with epoxy or molded for physical protection and pick-and-place machine compatibility. --- ## 4. Typical Applications These components are widely used in high-frequency circuits where small size and high reliability are required: * **RF Tuning:** Used in radio frequency circuits for filtering and impedance matching. * **Signal Conditioning:** Decoupling and noise suppression in communication devices. * **Mobile Electronics:** Smartphones, tablets, and wearables due to the compact 1008 footprint. * **Power Management:** Small-scale DC-DC converters. ---
