Electromagnetic (EM) radiation from inductors in DC/DC converters is no triviality — especially when considering the type and proximity of surrounding components and their susceptibility to magnetic coupling. In this post, we will discuss EM radiation as it pertains to unshielded, semi-shielded, and shielded inductors. We will also cover how EM radiation changes according to different influences.
