The CL1208-4-100TR-R is a common mode choke manufactured by Cooper Bussmann (now Eaton). It's designed to suppress common-mode noise in various electronic circuits and power lines. Common-mode chokes are essential components for reducing electromagnetic interference (EMI) and ensuring signal integrity.

Applications

• Power Line Filtering: Used to filter out common-mode noise from AC power lines entering electronic devices.
• Signal Line Filtering: Suppresses common-mode noise on signal lines, such as USB, Ethernet, and data communication cables.
• Switching Power Supplies: Reduces EMI generated by switching power supplies.
• LED Lighting: Filters noise in LED lighting systems to prevent interference.
• Audio Equipment: Improves audio quality by reducing noise on audio signal lines.

Features

• High Common Mode Impedance: Provides effective suppression of common-mode noise.
• Low Differential Mode Impedance: Minimizes signal attenuation for differential signals.
• Compact Size: Allows for integration into space-constrained applications.
• High Current Capability: Can handle significant current without saturation.
• Wide Frequency Range: Operates effectively over a broad frequency range.

Benefits

• Reduced EMI: Minimizes electromagnetic interference, preventing disruption to other electronic devices.
• Improved Signal Integrity: Enhances the quality of signals by reducing noise.
• Compliance with Regulatory Standards: Helps meet EMI/EMC regulatory requirements.
• Enhanced System Performance: Improves the overall performance of electronic systems by reducing noise.
