The SS20H-R10100 is a common mode choke designed and manufactured by Kemet. As part of the SS series, it is primarily used to suppress common mode noise in electronic circuits, thus improving signal integrity and reducing electromagnetic interference (EMI). This choke is carefully engineered to offer high common mode impedance while maintaining a low differential mode impedance, ensuring that the desired signal is not significantly attenuated.

Applications:

• USB Interfaces: Filtering common mode noise on USB data lines to ensure reliable data transfer.
• Ethernet Connections: Reducing noise on Ethernet cables to maintain stable network performance.
• LVDS Signal Lines: Suppressing common mode noise on LVDS (Low Voltage Differential Signaling) lines in display interfaces and high-speed data transmission.
• CAN Bus Systems: Protecting CAN (Controller Area Network) bus communication in automotive and industrial applications from noise.
• Power Lines: Filtering common mode noise in DC power lines to prevent interference with sensitive electronic components.

Features:

• High Common Mode Impedance: Provides effective attenuation of common mode noise across a wide frequency range.
• Low Differential Mode Impedance: Minimizes signal distortion and maintains signal integrity.
• Compact Size: Allows for easy integration into space-constrained applications.
• Surface Mount Design: Facilitates automated assembly and reduces manufacturing costs.
• RoHS Compliant: Meets environmental regulations by restricting the use of hazardous substances.

Benefits:

• Improved Signal Integrity: Reduces noise and interference, resulting in cleaner and more reliable signals.
• Enhanced System Performance: By filtering out unwanted noise, the overall performance of the electronic system is improved.
• Reduced EMI Emissions: Helps to meet regulatory requirements for electromagnetic compatibility.
• Increased Reliability: Protects sensitive electronic components from damage caused by noise and interference.
• Space-Saving Design: Its small size allows for easy integration into compact devices.
