Common Mode Chokes are devices that are used to prevent the interference generated by high frequency signals in capacitances. They work by creating a magnetic field that limits the transfer of the signals from one circuit to the other. Common Mode Chokes are predominantly used in the automotive industry, for example in cars for controlling the power supply. This means that they are widely used for systems that require low interference and deliver a good signal to noise ratio. One of the most common types of common mode chokes is the RS512-4-02. This type is a cylindrical type with a ferrite core. This model was designed for a low inductance and is suitable for big variation of applications. It has a maximum operating current of up to 2A when mounted on a flat surface and up to 4A when mount on a round surface.The working principle of the RS512-4-02 is based on the basic concept of a common mode choke. In the simplest terms, when two wires are placed together passing alternating current through them, a magnetic field is created. This magnetic field allows the transfer of the current from wire to wire, but it also disrupts it, causing interference. The RS512-4-02 works by wrapping both of the wires together in a cylindrical peripheral. This wrapping around the wires is filled by a ferrite core, which increases the inductance of the field generated by the current. This increases the magnetic field, which limits the amount of alternating current that can be passed through both of the wires. This is especially useful in applications that require low power consumption, such as automotive applications, where the RS512-4-02 operates under the assumption that the noise does not affect the performance of the inner wiring that will transfer the signal. Furthermore, this type of common mode choke also offers an advantage in that the noise is blocked more drastically as the signal frequency increases, meaning it is more effective against signals at higher frequencies than lower ones.Other applications of the RS512-4-02 make use of this increased effectiveness and low power demands. In optical signal transmission, the RS512-4-02 can be used to filter out noise signals while still allowing for the reliable transmission of the incoming optical signal. This means that the signal can be delivered over long distances without being affected by noise interference. In general, the use of common mode chokes is growing and becoming more popular with each passing day. This is due to their increasing effectiveness, ease of use and the number of applications that they are suited to. With the RS512-4-02 in particular, the cylindrical design, low inductance and efficient magnetism of its ferrite core make it the perfect choice for a variety of automotive and optical signal transmission applications.
