高频扼流圈是一段未闭合的铜，和其终端等效的边缘电容形成一个低通滤波器，可以有效地滤除馈入信号中的高频成分。
It acts as the LPF, effectively eliminating the high frequency component in the feed-in signal. The groove in the central region working as a loading capacitance in the open end is also discussed.

共模扼流圈的高频特征极大地影响了电磁干扰（EMI）滤波器抑制传导EMI噪声的性能。
The high frequency parasitic parameters of common mode(CM) choke significantly influence the performance of electromagnetic interference(EMI) filter for conducted EMI suppression.

高频扼流圈
高频扼流圈是指线圈有的绕在铁氧体芯上，有的是空心的，匝数为几百或几十，自感系数为几毫亨。高频扼流圈这种扼流圈只对高频交变电流有较大的阻碍作用，对低频交变电流的阻碍作用很小，対直流的阻碍作用更小，因此可以用来“通直流，阻交流，通低频，阻高频”。
