Common Mode Chokes (B82731T2351A020)

Common Mode Chokes (CMC) are electrical components used to limit and suppress common mode interference in circuits. The B82731T2351A020 CMC is a type of low-frequency common mode choke used in applications such as power supplies, switching converters, electronic measuring and industrial control systems. It is designed to reduce common mode interference, improve signal-to-noise ratio, increase power factor, and improve stability.

Application

CMCs are widely used in various types of circuits and applications. In switching converters, CMCs are used to limit common mode interference and reduce the risk of EMI (Electro-Magnetic Interference) disturbances. In power supplies, CMCs are used to limit common mode noise and improve power factor. In electronic measuring systems, CMCs are used to improve the signal-to-noise ratio of the circuit and stabilize the signal. CMCs are also used in industrial control systems to reduce common mode interference and ensure reliable operation of actuators and sensor switches.

Working Principle

Common Mode Chokes are passive inductors which work by limiting and suppressing common mode interference in circuits. These chokes consist of two coils wound close together on a common magnetic core. When exposed to a common mode current, the CMC creates a small magnetic field, which opposes and repels the current. The inductive opposition of the CMC creates a voltage drop across its terminals, limiting the current and suppressing noise. The CMC also works to improve the power factor, by increasing the inductive impedance of the circuit and limiting the current.

Conclusion

Common Mode Chokes (CMCs) are a type of low-frequency common mode filter used in various types of circuits and applications. The B82731T2351A020 CMC is a widely used component in power supplies, electronic measuring systems, and industrial control systems. CMCs work by limiting and suppressing common mode interference, improving the signal-to-noise ratio and power factor, and stabilizing the signal.
