Hi, All
I noticed that on my notebook DC power cable there is a cylinder between the DC converter and the output plug on my notebook. And on many consumer electronics products such as Digital camera, that cylinder object also exists. I guess that there is a EFT choke coil inside it. Is that right? If so, is there any information on that? For example, Standard, Spec, Product Ads...
I am interested on that because recently I am doing a project for suppress EFT on nano order. Neither diode or TVS could suppress that kind of EFT.
Thanks and Regards
Roger
