Common Mode Chokes, as the name suggests, are components designed to reduce noise of a type that documents refer to as "common mode". Specifically, they are used to reduce noise, in both power supplies and signal lines, caused by the electromagnetic coupling of parallel systems. The RN232-2.5-02 is an example of one such device that employs Common Mode Choke principles and specification.

Application Field

The RN232-2.5-02 Common Mode Choke is a small size, high performance unit that is specifically geared towards the networking market. It is used to reduce noise in both low- and high-end Ethernet networks, as well as providing isolation between unbalanced data lines and USB signals. While primarily designed for networking applications, it is also suitable for other applications, such as power supplies, control circuits, and communication circuits.

The RN232-2.5-02 has been largely popular in networking applications due to its small form factor and high-frequency response, allowing it to be used for applications such as cable, wireless, switches, routers, and fiber optics. It is also used in industrial, medical, consumer electronics, radio, and automotive applications.

Working Principle

The RN232-2.5-02 utilizes a three-pole design that covers a wide spectrum from 3 MHz to 1 GHz. It employs a three-level symmetrical configuration that provides impressive noise suppression and low insertion loss, when compared to devices with two poles or multiple levels of symmetrical configurations. The choke inclues two coils and two ferrite beads.

The RN232-2.5-02\'s two coils suppress noise and prevent interference by creating a magnetic field that cancels out noise. This process is often referred to as Counter Electro Motive Force, or CEMF. The two ferrite beads provide additional noise suppression and prevent interference by absorbably dissipating energy as opposed to reflecting it.

The RN232-2.5-02 also includes two capacitors that help reduce radiated interference from 50 MHz to 1 GHz, as well as improve high frequency response. The capacitors are connected across the coils and absorb energy from the common mode energy, thereby reducing common mode noise.

In addition to these components, the RN232-2.5-02 includes an insulating layer around the unit to protect against potential damage from EMI and RFI. This layer also acts as an additional shield against common mode noise.

Conclusion

The RN232-2.5-02 is an example of a common mode choke that is designed for use in the networking market. It uses a three-pole design with two coils, two ferrite beads, and two capacitors to reduce noise and interference. The unit also includes an insulating layer to help protect it from EMI and RFI. This combination of components provides excellent noise control and low insertion loss, making the RN232-2.5-02 a highly effective noise control solution for low- and high-end Ethernet networks as well as other applications.
