Common Mode and Differential Mode Filters to limit EMI Issues
This EMI filter includes a common-mode filter and a differential-mode filter. Generally Differential mode filter filters noise less than 30MHz and Common mode filter filters noise from 30 MHz to 100 MHz. Both filters have an effect on the entire frequency where EMI needs limiting.
