Common Mode Chokes (CMCs) are components used to suppress common mode noise. The CMT-8116 is a type of CMC designed to provide wide frequency noise suppression with high common mode impedance characteristics. It can be used in many different applications, from low frequency differential-mode noise suppression to high frequency common mode noise suppression.

The CMT-8116 is a two-winding, surface mount device that provides wide frequency noise suppression with high common mode impedance characteristics. It is typically used when board space is limited or for applications that require more convoluted routing of signal and power traces. The device features an operating temperature range of -55 °C to 125 °C, a standard shielding material, and a wide frequency response range. It is suitable for high frequency common mode noise suppression applications, such as mobile phones and MP3 players, as well as low frequency differential-mode noise suppression applications, such as LANs, audio systems, and computers.

The CMT-8116 features an optimized ferrite core material that provides high common-mode impedance characteristics without increasing the device’s size. This ferrite core material is designed to provide low conducting current and high insulation resistance. The device supports up to three counter-wound windings, achieving common mode impedance levels up to 50 ohms across the frequency range of 100 Hz to 1.0 MHz. The CMT-8116 is available in three sizes: 9 mm, 10 mm, and 12 mm.

The working principle behind the CMT-8116 is based on Faraday\'s Law of Electromagnetic induction. As a current flows through the windings of the CMC, it creates a magnetic field. Since there is a relative motion between the windings of the CMC and the current created, this magnetic field generates a voltage in the windings. This voltage generated by the CMC is used to suppress common mode noise. In order to ensure higher common mode impedance levels, the CMC is designed to maximize the magnetic flux and minimize eddy current losses in the windings.

The CMT-8116 provides high common mode impedance levels, low conducting current, wide noise suppression in a wide frequency range, and an operating temperature range of -55°C to 125°C. It can be used in a variety of applications, from low frequency differential-mode noise suppression to high frequency common mode noise suppression. The optimized ferrite core material of the CMT-8116 is designed to provide higher levels of common-mode impedance and lower levels of eddy-current losses without increasing the size of the device.
