The best way to design a filter is to establish the performance criteria first. Determine the source impedance Determine the load impedance Determine the attenuation required and at what frequency Determine the roll-off required Now you can determine what order filter you need and whether it is

Dear groupe, Does anyone have some good idears about designing a simple filter for surges (the kind of surges that comes from testing according to IEC 61000-4-5) I was thinking about using an inductor, a capacitor and a MOV. But, what is the requirements for the inductor ? and will it
