Common mode chokes are one of the most widely used electronic components in the modern electronics industry. They are commonly used to suppress common-mode noise and interference in power lines, signal lines and data lines. CMT-8104 is a typical common mode choke with wide application fields.Since CMT-8104 choke is manufactured with high temperature process, it performs extremely stable and has high reliability. The product is mostly employed to suppress common-mode noise between two different kinds of device and transmission line in car industry, home appliances, factory automation equipment and so on. Usually, choke like CMT-8104 is installed in power or signal cable harness. Compared with common filter, common mode choke provides better noise suppression.In addition, CMT-8104 choke has strong impact and high voltage resistance, which makes it applicable to noisy environments. This kind of common mode choke is suitable for noise suppression equipment, LED drivers, power supplies and other general purpose communication equipment with low frequency.The working principle of CMT-8104 common mode choke lies in the fact that the choke can induce magnetic flux to generate an electromotive force when the input differential signal is subject to varying current. Thus, the electromagnetic field generated by the choke can block the noise along with it. The choke not only blocks the differential-mode noise, but also suppresses the noise in the common-mode, which are perpendicular to the conductors. It works to block the signal interference caused by its own generated magnetic field with the line.The construction of CMT-8104 common mode choke is quite simple. It consists of a core material, a high-frequency capacitor and a few turns of wire wrapped around the core as an inductor. The internal capacitor and inductor are connected in series on each input or output line of the choke which helps to reduce or even eliminate the effect of high frequency disturbance signals in a circuit.Compared with other chokes, this type of common mode choke has a longer life span and higher current rating and temperature rating. Generally, CMT-8104 choke can tolerate up to around 100A, and its operating temperature range is 2019 degree to +105 degree.In summary, CMT-8104 common mode choke has wide application field and is capable of suppressing common-mode noise in power and signal cables. The design and construction of this choke is quite simple, thus it is durable and reliable. Moreover, it is highly resistant to high voltage and current, making it suitable for a variety of noisy environments.
