The B78417A8207A-3 is an EPCOS (TDK) common mode choke. Common mode chokes are used to suppress common-mode noise in electronic circuits. Common-mode noise is unwanted electrical noise that appears simultaneously on multiple conductors with respect to a common reference, such as ground.

Applications:

• Power line filters: Reduces noise conducted along power lines, preventing interference with other devices.
• USB interfaces: Suppresses noise in USB data lines to improve data integrity.
• CAN bus systems: Filters noise in automotive and industrial CAN bus networks.
• Signal lines: Reduces noise in audio, video, and data signal lines for cleaner signal transmission.
• Switching power supplies: Minimizes common-mode noise generated by switching power supplies.

Features:

• High common-mode impedance: Effectively blocks common-mode noise while allowing differential signals to pass through.
• Low differential-mode impedance: Minimizes signal distortion in differential signal lines.
• Compact size: Enables easy integration into various circuit designs.
• RoHS compliant: Meets environmental standards for restricted substances.
• High insulation voltage: Provides isolation between the windings and the core.

Benefits:

• Reduced electromagnetic interference: Improves the performance and reliability of electronic devices.
• Cleaner signal quality: Reduces noise and distortion in signal lines.
• Improved data integrity: Ensures reliable data transmission in digital communication systems.
• Compliance with regulatory standards: Helps to meet EMI/EMC requirements for electronic products.
• Enhanced system stability: Improves the stability and reliability of electronic circuits.
