Common Mode Chokes (CMC) are electromechanical components used to reduce electromagnetic interference (EMI) in a variety of electrical circuits. CMCs are primarily used to control the transmission of high frequency energy from one device to another. This is done by providing an impedance between the two devices, which helps to reduce the amount of radio frequency noise that may be generated. Common Mode Chokes also help to reduce ground loop currents, which can cause undesired electrical behavior.

CTX66-19447-R common mode chokes are commonly used in modern electronic devices, such as computers, televisions, stereos, and cell phones. These CMCs offer a high level of impedance in the common-mode, while still allowing a very low DC resistance. The inductance range of these components is from 10nH to 1mH. The inductance of the CMC is usually determined using a chart of per-pin impedance rather than the traditional inductance rating. This type of component is also very compact, and can fit into very small spaces.

The main advantage of CTX66-19447-R common mode chokes is that they can reduce the amount of EMI produced in a device, and thus reduce the amount of interference that is radiated out into the environment. CMCs are typically used in automotive and industrial applications, where high levels of interference can be potentially harmful. CMCs are also used in consumer applications, in order to reduce the amount of RF interference that is generated by cell phone base stations or Wi-Fi routers. CMCs can also be used in systems to reduce the amount of ground loop current, as well as in sensitive electronic systems that are sensitive to EMI.

The working principle behind a CMC is quite simple. They are designed to provide a high impedance in the common mode, while still providing a low DC resistance. This is done by utilizing a large number of windings, which are wound around a metal core. The windings are designed in such a way that the impedance is increased when current flows through them. This helps to reduce the amount of high frequency energy that is transmitted to other components in the circuit.

In conclusion, CTX66-19447-R common mode chokes are a useful tool for reducing the amount of EMI generated in a circuit. They are very compact, and can be used in a variety of applications, such as automotive, industrial, and consumer electronics. By providing a high level of impedance in the common mode, CMCs help to reduce the amount of interference that can be radiated out into the environment. Additionally, CMCs can be used to reduce ground loop current and help to protect sensitive electronics from potentially damaging levels of EMI.
