The SC3-118RFI is a common mode choke manufactured by TT Electronics. These chokes are designed to suppress common-mode noise in electronic circuits, which is crucial for maintaining signal integrity and complying with electromagnetic compatibility (EMC) regulations. They effectively attenuate noise that is common to multiple lines while allowing differential signals to pass through with minimal attenuation.

Applications:

• Power line filtering
• Data line filtering (e.g., USB, Ethernet)
• Signal line noise suppression
• Motor control circuits
• Industrial automation equipment
• Medical devices

Features:

• High common mode impedance for effective noise suppression
• Low differential mode impedance to minimize signal distortion
• Compact size for space-constrained applications
• High current handling capability
• Wide operating temperature range
• RoHS compliant

Benefits:

• Reduced electromagnetic interference (EMI)
• Improved signal integrity
• Enhanced system reliability
• Compliance with EMC regulations
• Minimized noise coupling between circuits
• Protection of sensitive electronic components

Additional Details:

The SC3-118RFI common mode choke features a ferrite core, which provides high impedance to common-mode currents. It is typically used in circuits where common-mode noise is a concern, such as power supplies, data communication lines, and signal processing circuits. Key specifications include the common-mode impedance, differential-mode impedance, rated current, DC resistance, and insulation voltage. Refer to the TT Electronics datasheet for detailed electrical characteristics, physical dimensions, and application guidelines. The choke is designed for surface mount assembly, allowing for easy integration into automated manufacturing processes.
