As an EMI high frequency attenuation element, it is implemented by stacking
the ferrite sheets printed with Inner Electorde.
This product implements high impedance in a small size, so it is effective in suppressing Noise.
The structure diagram is as follows.
The common mode filter is a structure in which two inductors are combined by winding two identical coils together.
It is a passive component that passes the signal current in differential mode and removes only the noise current in common mode.
The structure diagram is as follows.
