Common Mode Chokes, such as the RN232-4-02, are inductors that are used to suppress common mode noise in high speed circuits while allowing the differential pairs to pass through. Common mode chokes are typically used in high frequency applications, such as wireless communication, as they limit the amount of noise that can be introduced into the system. The RN232-4-02 can be used in a variety of applications, including automotive, industrial, security, medical, and consumer electronics.

In the case of the RN232-4-02, the inductor is designed using a proprietary material that delivers the optimal combination of low resistance, low inductance, and high current carrying capacity. This combination of characteristics allows the RN232-4-02 to perform up to its rated frequency of up to 4GHz while maintaining a low DC resistance of 4.2 Ω. The inductor is also designed to be used in differential pair communication links, such as Ethernet and USB, as well as other high data rate applications.

The principles of working of the Common Mode Choke are relatively simple. The inductor is placed between the source and the receiver, and any common mode noise is intercepted by the inductor. The inductor then creates an impedance to the noise, which prevents it from travelling downstream to the circuit or system.

The RN232-4-02’s construction also offers high common mode attenuation over the entire frequency range, meaning that it can effectively stop noise from entering the circuit. The inductor also offers exceptional performance when placed in the right circuit. The inductor’s tightly coupled coils effectively suppress any EMI/RFI interference, allowing the circuit to operate effectively in high-frequency applications.

With its ability to intercept common mode noise, the RN232-4-02 is an ideal choice for high speed circuits such as wireless communication systems, and it is suitable for a variety of industrial and consumer applications. The inductors small size also makes it suitable for use in tight spaces, and the low resistance, low inductance, and high current carrying capacity make it suitable for use in high data rate systems. By using the RN232-4-02, engineers can ensure that their systems are protected from interference, and that their high-speed circuits can operate effectively and reliably.
