Function of Small cylinder in the middle of the cable charger (ferrite bead)
| May 09, 2016 |
What is the actual function of the cylinder on a mobile phone charger or laptop?
If you notice, some congenital charger cable phone or laptop equipped with a cylinder that stands out near the end of the port. Indeed, not all the factory default charger cable is not equipped with these devices, although some users are troubled by the cylinder for a little inconvenient when about to be taken away.
Do not rush to underestimate the additional devices, because in fact he is carrying out a very important task. What exactly is the function of the cylinder? What is inside it? Well, than you are curious, just peep the pictures below ...
Stood out and made the charger cord so hard to bend, actually this cylinder has a very important task.
Not only in mobile phones, some laptop charger also has a cylinder near the port. What the heck does it do?
The electronic circuit can create noise that disturb the ears and the concentration of people who are nearby. This is the function of a cylinder called the ferrite bead.
It was able to reduce the noise caused by electromagnetic waves at a meeting of the AC and DC currents.
From the outside it is the material looks similar to a cable. But if it is opened, the inside of the ferrite bead is made of a mixture of ceramic, iron oxide and some other metal material.
The ferrite bead also serves to block the radio frequency devices that are too high, so that did not participate charger cable transmits or receives a signal that it could have negative consequences on the device.
