The **MV61V2AG-R** is a specific part number typically associated with **Common Mode Chokes (Filters)**, often utilized in high-speed data line applications like HDMI, USB, and MIPI interfaces. These components are critical for suppressing Electromagnetic Interference (EMI) without degrading signal integrity. --- ### 1. Component Overview The device is a surface-mount (SMD) magnetic component. Its primary function is to block high-frequency noise that is common to both signal lines (common mode) while allowing the actual data (differential mode) to pass through. ### 2. Technical Specifications Below are the typical technical characteristics found in this series of components: | Feature | Specification (Typical) | | :--- | :--- | | **Component Type** | Common Mode Choke / EMI Filter | | **Impedance (@ 100MHz)** | 60 $\Omega$ to 90 $\Omega$ (varies by sub-type) | | **DC Resistance (RDC)** | < 0.5 $\Omega$ | | **Rated Current** | 100mA - 300mA | | **Rated Voltage** | 5V - 20V DC | | **Operating Temperature** | -40°C to +85°C | | **Package Size** | 0605 or 0805 (Metric equivalent) | --- ### 3. Internal Structure and Working Principle The part consists of two coils wound around a single ferrite core. * **Common Mode Noise:** Noise traveling in the same direction on both lines creates magnetic fields that add up in the core, creating high impedance and "choking" the noise. * **Differential Signal:** The data signals travel in opposite directions; their magnetic fields cancel out, allowing the signal to pass with minimal attenuation. --- ### 4. Typical Applications The MV61V2AG-R is commonly found in the following electronic circuits: 1. **USB 2.0/3.0 Ports:** To prevent EMI radiation from high-speed data switching. 2. **HDMI/DisplayPort:** Maintaining signal purity for high-definition video. 3. **Mobile Devices:** Reducing noise in camera (MIPI) and LCD interfaces. 4. **CAN Bus:** Suppressing noise in automotive communication lines. --- ### 5.
