Customized High Power Filter Inductors

In fact, if one end of the filter circuit is connected to the interference source, the other end is connected to the interfered device, then La and C1, Lb and C2 constitute two sets of low-pass filters, which can make the common mode EMI signal on the line be controlled at a very low level. This circuit can not only suppress the external EMI signal incoming, but also attenuate the EMI signal generated when the line itself works, which can effectively reduce the EMI interference intensity.

A small common mode inductor manufactured in China has the advantages of high frequency noise suppression strategy, common mode choke coil structure, no signal attenuation, small size, easy to use, good balance, easy to use, high quality and so on. Widely used in double balance tuning devices, multi-frequency transformers, impedance transformers, balanced and unbalanced conversion transformers... And so on.

There is also a common mode filter inductor /EMI filter inductor using ferrite core, double line and wound, noise suppression strategy is best, high common mode noise suppression and low difference mode noise signal suppression, low difference mode noise signal suppression interference source, in the high-speed signal is difficult to deform, small size, with good balance, easy to use, high quality and other advantages. Widely used in the suppression of electronic equipment EMI noise, personal computer and peripheral equipment USB line, DVC, STB IEEE1394 line, LCD panel, low-voltage differential signal... And so on.
