Common Mode Chokes

Common Mode Chokes (CMCs) are electronic components which are used for suppressing electromagnetic interference (EMI) in radio-frequency applications. They are also known as common-mode filters, line filters, chokes, or differential-mode filters. CMCs are typically used along with other components such as capacitors and resistors to form a complete EMI filter.The CMT-8108-B is a type of Common Mode Choke (CMC) which is used in a variety of industrial, consumer, and automotive applications. It is designed for 300kHz-1GHz frequency range and can handle up to 1A of current. The CMT-8108-B has an axial-leaded package, with different pin sizes, lengths and diameters. Its package also features an optional snap-in design which makes assembly easier.The working principle of the CMT-8108-B is based on the principle of mutual inductance. This type of component is designed to reject common mode interference signals, while allowing the transmission of differential mode signals. Differential mode signals refer to the signals that have two components which are in opposite directions. Common mode signals, on the other hand, refer to the signals that have two components which are in the same direction. CMCs create a high impedance in the common mode circuit and a very low impedance in the differential mode circuit. This allows for high rejection of common mode interference signals, while allowing the transmission of differential mode signals.The applications for the CMT-8108-B include industrial, consumer and automotive markets. It is often used as part of an EMI filter in automotive applications. It is also used in industrial and consumer applications, such as power supply regulation, data line protection, Ethernet line protection, and noise suppression in switch-mode power supplies.The CMT-8108-B has several advantages which make it an attractive choice for application in the above mentioned fields. It has a high common-mode attenuation (up to 50dB @ 1GHz), an excellent differential rejection (up to 60dB @ 1GHz), a wide frequency range (300 kHz to 1 GHz), and a high current capability (up to 1A). It is also compact, making it suitable for use in space-constrained environments.In conclusion, the CMT-8108-B is an ideal choice for EMI filtration or suppression in industrial, consumer, and automotive applications. It provides high common-mode attenuation, excellent differential rejection, and wide frequency range with high current capability. It is also compact and easy to assemble, making it suitable for use in space-constrained applications.
