When the inductance of the two common mode choke coil is the same, the smaller value is selected according to the definition of Q value (XL / R), or the selection value is the same and the diameter is large. In other words, the larger Q value is used. Then the quality factor Q value is adjustable, then how is he raised it?
First, the material to solve the problem - use high-quality coil skeleton, reducing…
