Common Mode Chokes are electronic components commonly used in the production of electronics and radio frequency (RF) devices. In particular, they are often used to limit or attenuate the flow of unwanted or undesired power or noise in fields such as telecommunications and medical devices. The EXC-14CT900U is a particularly useful example of a common mode choke. In this article, we will discuss its various application fields, as well as its working principle.

EXC-14CT900U Application Fields

The EXC-14CT900U is designed primarily for use with applications that require a high level of noise control, such as mobile and wireless communications, medical imaging, and unmanned aerial vehicles (UAV) or drones. By filtering out noise, it helps to ensure that frequencies within the designated range do not interfere with the operation of the device. Furthermore, it also helps to prevent the device from interfering with other nearby electronic components.

The EXC-14CT900U is able to maintain its shield effectiveness at high frequencies, up to 10 GHz, which is something many other common mode chokes are not able to do. This makes it particularly well-suited to applications in which there are a variety of frequencies that need to be filtered out. It is also suitable for use in environments with high temperatures, as it is able to maintain its shielding capabilities even when subject to temperatures as high as 150°C.

EXC-14CT900U Working Principle

The EXC-14CT900U is based on the principle of inductive coupling. In this type of coupling, an inductor is placed near an electric conductor, and an electromtoive force is generated when a current flows through the circuit. This force is responsible for the blocking of unwanted signals in the system.

The EXC-14CT900U utilizes the concept of mutual inductance, which occurs when the magnetic field generated by one inductor causes a current to be induced in the other. This current then produces its own magnetic field which is in turn used to block unwanted signals. Mutual inductance is the reason for the EXC-14CT900U’s ability to effectively reduce noise and interference even in high frequency applications.

The EXC-14CT900U also features a closed loop design, which helps to reduce the possibility of ambient noise leakage. This element also helps to ensure that the device maintains its shielding capabilities even at high temperatures.

Conclusion

The EXC-14CT900U is a particularly effective common mode choke, and is highly suited to applications in the fields of mobile and wireless communications, medical imaging, and UAVs. Its working principle relies on principles of inductive coupling and mutual inductance, while its closed loop design helps to prevent noise leakage and ensure that the device maintains its performance even at high temperatures.
