Common Mode Chokes

Common Mode Chokes, abbreviated as CMC, are electrical components that have the property to transmit direct current but impede or impede the flow of alternating currents. The RN112-0.5-02-18M, a type of common mode choke, has a wide range of applications and works on the principle of mutual inductance. This article will explain its field of application and working principle.

Application Field of RN112-0.5-02-18M

Common mode chokes like the RN112-0.5-02-18M are mainly used for power filters to prevent high frequency noise generated by switching power supplies, motors, inverters, etc. from propagating outside a device or system and interfering with other circuits. In addition, the RN112-0.5-02-18M can also be used for various types of signal processing operations such as power line communication, pulse signalfiltering, overcurrent protection, phase detection, and soft start circuit protection.

Working Principle of RN112-0.5-02-18M

RN112-0.5-02-18M operates on the principle of electromagnetism, specifically mutual inductance. When connected to the power supply or other device, electrically conducting wire coils generate an electromagnetic field in the surrounding magnetic material. This magnetic field creates a change in the flux of the electric current, thus amplifying or reinforcing the voltage or current in the circuit. The mutual inductance of the CMC involves voltage and current flowing through the wires wrapped around the core at the same time, thus allowing the CMC to filter only the noise or the voltage fluctuations while allowing the direct current to pass freely.

Conclusion

In conclusion, RN112-0.5-02-18M is a type of common mode choke that is widely used in power filters for preventing high frequency noise, signal processing operations such as power line communication, pulse signal filtering, overcurrent protection, phase detection, and soft start circuit protection. It works on the principle of mutual inductance, where the magnetic field created by electrically conducting wire coils generate a change in the flux of the electric current in order to amplify or reinforce the voltage or current.
