The **XFWICS1008-R10** is an electronic component primarily identified as a **Surface Mount (SMD) Wire-Wound Chip Inductor**. It is part of the 1008 series, which refers to its physical dimensions. --- ### 1. Key Technical Specifications The part number follows a standard naming convention for inductors. Here are the core specifications: | Parameter | Value / Detail | | :--- | :--- | | **Inductance** | 100 nH (Nanohenries) | | **Tolerance** | Usually ±5% or ±10% (depending on specific suffix) | | **Package Size** | 1008 (2.5 mm x 2.0 mm) | | **Type** | Wire-wound Ceramic Core | | **Mounting Type** | Surface Mount Device (SMD/SMT) | ### 2. Breakdown of the Part Number * **XFWIC:** Series prefix (often associated with high-frequency wire-wound inductors). * **1008:** Physical size code (Imperial: 0.10 x 0.08 inches). * **R10:** The inductance value. "R" acts as a decimal point in microhenries ($\mu H$). * $0.10\mu H = 100nH$. ### 3. Construction and Material These components are typically constructed using a **Ceramic Core** with fine copper wire wound around it. * **Ceramic Core:** Provides excellent signal transparency and high "Q" (Quality Factor) at high frequencies. * **Wire-Wound Design:** Offers significantly lower DC Resistance (DCR) and higher current handling capabilities compared to multilayer inductors. ### 4. Common Applications Due to its high resonance frequency and stability, this part is used in: * **RF Circuits:** Matching networks and filters in wireless communication. * **Mobile Devices:** Bluetooth, Wi-Fi modules, and GPS receivers. * **Broadband Equipment:** High-frequency signal processing and decoupling. --- ### 5. Performance Advantages 1. **High Self-Resonant Frequency (SRF):** Allows the component to maintain inductive properties at very high frequencies. 2. **High Q Factor:** Results in low signal loss, making it ideal for narrow-band filters. 3. **Stability:** Ceramic cores are highly stable against temperature fluctuations.
