Common Mode Chokes (CMCs) are components that are involved in the management of EMI in electronic systems. They help prevent unwanted electromagnetic interference (EMI) from traveling through the signal or power wires and into the sensitive electronics of the system. The RN122-4-02 CMC from Ferroxcube is a DC-rated, third-generation choke designed for use in power management applications where magnetic saturation is an issue. The RN122-4-02 model is particularly suited for automotive and medical applications.
Application Field
The RN122-4-02 CMC can be used in various power and data management applications, including automotive, medical, industrial, and telecom supply. Its superior characteristics ensure that it performs well in all of these applications. It is especially suitable for automotive and medical applications as it helps reduce the variation in ripple current and noise produced by vehicular ignition systems and medical equipment. Additionally, its low saturation resistance ensures that it can handle sudden current spikes without issue.Working Principle
Common Mode Chokes accomplish their purpose by preventing common-mode noise currents from entering sensitive circuits. They achieve this by creating a low-impedance path for the current, thus limiting the amount of current that can flow and substantially attenuating the voltage. Generally, this is done by winding a wire in a continuous loop or coil and having two of the ends of the coil connected to the input of the device. At the same time, the coil creates a high impedance field between its turns, thus blocking the transmission of any external noise. The resulting device is known as an inductor or choke.In the case of the RN122-4-02, it is constructed with two terminating wires and a toroidal ferrite core. This core helps ensure the low-impedance path for the current, while simultaneously creating a high impedance field around the device. This allows the device to effectively block the external noise and attenuate the amount of current that can flow through the circuit.Conclusion
The RN122-4-02 CMC is a high-quality, third-generation product designed for power and data management applications. Its application field covers automotive, medical, industrial, and telecom supplies. Its superior characteristics and low saturation resistance make it suitable for these high-power and demanding applications. Furthermore, its low-impedance path and high-impedance field allow it to effectively prevent the entrance of external noise into the sensitive circuits.The specific data is subject to PDF, and the above content is for reference
