It does take a great deal of 'interesting-ness' for me to post ona subject, however I really need to share this with you it has shall we say surprised myself to such a degree I had to ask three times so to let the realisation to fully sink in.

Let us look at the evidence, below is an image of some emc devices I had commissioned for a new project I am working on (it's a new medical device) anyway take a look, these interface between a power supply and a scanner / imager. 

Size wise they are 9mm in diameter and 0.75mm in thickness. They are designed as an EMC barrier and work well.

Don't ever complain audio is expensive (Mike music, look away now, it may induce heart palpatations)
