The part number **10VF-4G0-R** typically refers to a high-performance **common mode choke** or filter component, often produced by manufacturers like **Chilisin** or **Coilmaster**. These components are essential for electromagnetic interference (EMI) suppression in high-speed data lines. --- ### 1. Key Technical Specifications The "10VF" series is designed for surface-mount applications where space and noise reduction are critical. | Feature | Description | | :--- | :--- | | **Component Type** | Common Mode Choke / EMI Filter | | **Impedance** | Typically rated at 100MHz (Specific ohms vary by sub-version) | | **Current Rating** | Designed for low-power signal lines (e.g., 100mA - 500mA) | | **Mounting Type** | SMD (Surface Mount Device) | | **Package Size** | Usually 0402 or 0603 footprint (check datasheet for exact mm) | | **RoHS Status** | Compliant (Indicated by the "-R" suffix) | --- ### 2. Physical Construction The device is constructed using multilayer ceramic technology or wire-wound ferrite cores to achieve high impedance in a small form factor. * **Internal Structure:** Two coils wound in opposite directions on a single core. * **Termination:** Tin-plated electrodes for high-quality soldering. * **Encapsulation:** Ferrite material which provides magnetic shielding to prevent cross-talk. --- ### 3. Applications and Functions The primary role of the **10VF-4G0-R** is to filter out noise while allowing the desired signal to pass through. #### Core Functions: 1. **Common Mode Noise Suppression:** Eliminates unwanted signals that are common to both lines in a differential pair. 2. **Signal Integrity:** Maintains the shape of high-speed digital signals (USB, HDMI, MIPI). #### Common Uses: * **Mobile Devices:** Smartphones and tablets to prevent RF interference. * **Display Interfaces:** LVDS or MIPI D-PHY lines for high-resolution screens. * **Computer Peripherals:** USB 2.0/3.0 ports and high-speed data interfaces. --- ### 4. Part Number Breakdown (Typical) While manufacturers vary slightly, the nomenclature usually follows this logic: | Code | Meaning | | :--- | :--- | | **10VF** | Series designation (Multilayer Common Mode Filter) | | **4G0** | Impedance/Specification code (e.g., "4" implies specific frequency curve) | | **-R** | Lead-free / RoHS Compliant / Tape & Reel packaging | ---
