On Jul 12, 2016
#1 What's That For?
Many of us have absolutely no clue what the pieces on our electronic devices are for...because we're only worried if they work or not!
#2 Laptop Charger
Take your charger for example, have you ever realized there's an additional cylinder piece on the chord that seems to be there for no reason?
#3 Isolate Noise
Well it's actually used to isolate electro-magnetic noise, and block the cable waves or noise in AC-DC converter.
#4 EMI ring
This one small piece scatters currents in a ferrite ceramic, and is generally called a core, block, or EMI ring.
