Common Mode Chokes

Common mode chokes are designed to reduce common mode noise in power circuits. The RN214-1.5-02 is a high-performance common mode filter choke designed specifically to reduce electromagnetic interference (EMI) and maintain signal integrity. It provides increased power integrator and harmonic rejection while offering minimal current loss to the application.

Application Field

The RN214-1.5-02 is suitable for applications where common mode noise must be reduced. This includes:

• Computer motherboards and notebook PCs
• MotorControl and Power converters
• Data communications systems, such as Ethernet networks
• Medical equipment, such as anesthesia machines
• Industrial automation equipment
• Instrumentation and control systems
• Home appliances and vehicle electronics

Working Principle

Common mode chokes, like the RN214-1.5-02, are designed to isolate common mode noise from the circuit and reduce the noise level in the power circuit. It works by providing a low-impedance path for common mode currents, while creating a high-impedance path for differential mode currents. This allows the differential mode current, which is necessary to carry the signal or power, to pass through the choke while the common mode current is blocked.The RN214-1.5-02 also features an integrated ferrite core, which is designed to increase the choke\'s inductance and reduce common mode noise levels. The ferrite core helps reduce the number of external components needed, while providing additional shielding and EMI reduction. In addition, the RN214-1.5-02 also has an integrated circuit protection circuit, which helps protect the choke from short circuits and overvoltage conditions.

Conclusion

The RN214-1.5-02 common mode choke is designed to reduce common mode noise in power circuits. It provides improved power integrator and harmonic rejection, while also providing minimal current loss to the application. It is suitable for a wide range of applications, including computer motherboards, medical equipment, and industrial automation equipment. In addition, it provides an integrated ferrite core and integrated circuit protection circuit to provide additional shielding and EMI reduction.
