The **CI1008F-R01-KB** is a specific surface-mount electronic component, categorized as a **Wire-wound Chip Inductor**. It is commonly used in high-frequency circuits, RF communication devices, and signal processing applications. --- ## 1. Part Number Breakdown To understand the electronic characteristics, we can decode the manufacturer's part numbering system: | Segment | Meaning | Detail | | :--- | :--- | :--- | | **CI** | Series Code | Chip Inductor (Standard Wire-wound) | | **1008** | Case Size | 1008 (Metric 2520) - 2.5mm x 2.0mm | | **F** | Material/Type | Ferrite Core (Typically for higher inductance/current) | | **R01** | Inductance Value | R = decimal point. **0.01 µH (10 nH)** | | **K** | Tolerance | **±10%** | | **B** | Packaging | Bulk or specific reel (varies by manufacturer) | --- ## 2. Technical Specifications The CI1008 series is designed for stability and high performance in compact environments. Below are the typical electrical parameters for this specific 10nH model: ### Electrical Profile * **Inductance:** 0.01 µH (10 nH) * **Tolerance:** ±10% (K) * **Test Frequency:** Typically measured at 100 MHz. * **Quality Factor (Q):** Usually high (approx. 15-30) to ensure low signal loss. * **DC Resistance (DCR):** Low resistance (usually < 0.20 Ω) to minimize heat dissipation. * **Rated Current:** Capable of handling moderate current (approx. 500mA to 1000mA depending on specific brand thermal rating). --- ## 3. Physical Construction * **Core Material:** Ceramic or Ferrite. Given the "F" designation, this often indicates a ferrite core which provides higher inductance density. * **Termination:** Lead-free (RoHS compliant) solder pads, usually tin-plated over nickel. * **Encapsulation:** Often molded or coated in epoxy resin for environmental protection and mechanical strength during pick-and-place assembly. --- ## 4. Common Applications Due to its small footprint and 10nH value, this part is frequently found in: 1. **RF Matching Circuits:** Used to match impedance between antennas and transceivers. 2. **Filter Networks:** Low-pass or high-pass filters in wireless communication (Wi-Fi, Bluetooth). 3. **Decoupling:** Filtering high-frequency noise in power supply lines for sensitive ICs. 4. **Oscillators:** Serving as a frequency-determining element in LC circuits.
