We might be taking our charge cables for granted. Sure, we love how they charge our much needed and loved devices like our mobiles and tablets but besides that function we don’t know how much work went into the cord. One component of the charge cable is the small cylinder-like module. Usually this part is near the end of the cable. You will be surprised to find out what this unassuming piece does. Let’s just say this piece plays an important role in protecting your devices from slowly deteriorating.Most people have no clue what it is.
The thick part of the cord is not just there for decoration.
The cylinder near the end of the cable is actually there for a good reason.
The ferrite bead suppresses high frequency noise from electronic circuits. Therefore, electro magnetic noise and AC-DC noises are suppressed. Ferrite beads are also referred to as EMI filters, chokes, blocks, and rings.
The EMI ring is made up of ceramic compounds from iron oxide and other metals.
Cables work as antennas. Therefore, if a device has high radio frequencies this would pass through the wire. The choker blocks the cord from transmitting and receiving signals.
