Addressing Differential and Common Mode Noise With Innovative Dual-Mode Choke Technology

CMF Series Dual Mode Chokes

Circuit designers must deal with many types of noise: internal, external, RF, line frequency and more. Noise can be a limiting factor in system performance and so must be addressed and minimized. The question is “at what cost and effort?”  Is it better to sacrifice performance or cost?  In either
