The skills of common mode inductor selection

The skills of common mode inductor selection   Common mode inductance is a kind of inductance device widely used in electronic circuits, which is mainly used to filter and isolate common mode interference in circuits. This paper will introduce the skills of common mode inductor selection in detail. Common mode inductance performance The frequency of each circuit is different. The impedance of the circuit needs to be calculated by frequency. The impedance characteristic of a common-mode inductor is that its impedance increases with increasing frequency and is more significant in the high frequency range. When designing the circuit, it is necessary to consider the inductance value and impedance characteristics of the common mode inductor to ensure that the stability and anti-interference performance of the system has reached an ideal level. Common mode inductor line diameter selection The diameter of the common mode inductor is the diameter of the wire between the main coil and…
