Hi All,
I'm controlling several 220V AC appliances via an electromechanical relay and Arduino. The appliances include a 50W TV, a 300W device, and a 1.5KW air conditioner, these are all going to be controlled via a single relay. I've been reading about the problems of switching on and off inductive loads, and that it can reset MCUs and one of the solutions is to put a ferrite core in one of the AC line. I'd like to know what type of ferrite core should I use and the ratings that I need to look out for. Also how many turns of the AC line should I wound on the ferrite core for this to be effective? What I saw from another forum seems to be using similar to one of these:
