The Panasonic UNR9216GOL is a common mode choke coil designed to suppress unwanted common mode noise in electronic circuits. It is part of Panasonic's UNR series, which is known for its compact size and effective noise suppression. Common mode chokes are essential components for improving electromagnetic compatibility (EMC) and reducing electromagnetic interference (EMI) in various electronic devices.

Applications

• Power Supplies: Filtering common mode noise from AC or DC power lines.
• Data Lines: Suppressing noise on data lines such as USB, Ethernet, and HDMI cables.
• Audio Equipment: Reducing noise in audio signals to improve audio quality.
• Video Equipment: Filtering noise in video signals to enhance video clarity.
• Consumer Electronics: Improving the overall EMC performance of devices like TVs, set-top boxes, and gaming consoles.

Features

• Compact Size: Allows for easy integration into space-constrained applications.
• High Common Mode Impedance: Provides effective attenuation of common mode noise.
• Low Differential Mode Impedance: Minimizes signal distortion.
• High Current Capability: Can handle relatively large currents without saturation.
