Common Mode Chokes are a type of electrical filter. They are commonly used to reduce interference and eliminate electrical noise in different systems. The MCZ1210AD900T002 is a commonly used type of common mode choke with an estimated impedance of 8.87 Ω at 1 kHz. The following will look at its application field and working principle.

The MCZ1210AD900T002 is a surface-mount type common mode choke which is suitable for use in high-frequency DC/DC converters, switching power supplies and displays with operating frequencies of up to several GHz. It is mainly used to reduce the common-mode noise and improve the signal transmitting performance. It is also suitable for use in communication equipment, including mobile radios, cordless phones, and receivers. The MCZ1210AD900T002 is also particularly suited for signal line quality improvement in automotive applications.

Common mode chokes work by creating a filter that is placed in series with the signal lines. This filter blocks the common-mode interference but passes the signals without distortion or attenuation. The effect of the common mode choke can be explained using the equivalent series inductor model. This model assumes that the common mode current flow is a result of an inductor connected in series with the two signal lines.

The inductor and the capacitor form a resonant circuit in which the inductance is proportional to the mutual capacitance and the impedance of the common-mode choke will increase with frequency. The resistor in the equivalent model represents the parasitic resistance in the circuit due to losses in the inductor. By using this model of the common-mode choke, it is possible to calculate the reactance and resistance of the choke at different frequencies.

Common-mode chokes are used in many different applications. Their primary function is to reduce EMI and they do this by providing a high-impedance in the common-mode path and provide filtering for all the signal lines. As such, they are an essential component in helping to maintain signal integrity in many systems. The MCZ1210AD900T002 is a commonly used common-mode choke and has applications in a range of different systems.
