Common mode chokes are electric devices that suppress common mode noise or interference from signals carrying alternating current by acting as a filter. B82790S0253N201 is a type of common mode choke which suppresses noise in high-transmission speed systems and is ideal for applications in power supplies, automotive systems, and aircraft systems.

Application Field

B82790S0253N201 is mainly used in automotive, industrial and power applications, including:

• Inverter, motor and servo drives
• Electronic ballasts for lighting
• Uninterruptible power supplies
• Communication systems
• Elevator systems
• Air conditioning systems
• Body and cabin electronics

Working Principle

Common mode chokes are basically inductive components that suppress the common mode noise by creating a high resistance to low-frequency noise. B82790S0253N201 specifically works by fitting a number of inductive components into a single case, thus forming an inductive transformer meant to remove noise from the system. It blocks input signals from the power supply while allowing current to pass through, thus isolating the system from external disturbances.

B82790S0253N201 also utilizes ferrite beads to suppress common modely noise generated by the cable itself. The ferrite beads raise the impedance to high frequency noise. The beads are each wound with a few turns of insulated wire of the same size and placed in a ferrite assembly. The ferrite mixture is then encased in a plastic housing so that only the wire passes through, thus enabling the ferrite to reject any unwanted interference.

In conclusion, the B82790S0253N201 common mode choke is designed for suppression of common mode noise in high-transmission speed systems. It works by fitting a number of inductive components into a single case, and through the use of ferrite beads to increase its noise suppression capabilities.
