ever question what’s inside a surface-mount inductor? question no more as you view this SMT inductor teardown video.
“Teardown” isn’t truly precise here, at least by the basic of [electronupdate]’s other element teardowns, like his looks inside LED light bulbs and das blinkenlights. “Rubdown” is more like it here, since what starts out as a rather solid looking SMT element needs to be ground down bit by bit to expose the inner ferrite as well as copper goodness. [electronupdate] embedded the R30 SMT inductor in epoxy as well as hand lapped the whole thing up until the windings were visible. Of course, just peeking inside is never enough, so he set upon an analysis of the inductor’s innards. utilizing a bit cautious macro photography as well as some simple picture analysis, he verified the component’s data sheet claims; as an aside, is anyone else amazed that a small SMT element can handle 30 amps?
