What Is That Cylindrical Plastic Part In Our Cables?

Have you ever wondered what that cylindrical part in some cables does? Although we do not see it much on new devices, this piece, which we think everyone has seen at least once, roughly protects your device from unwanted signals. Let’s take a look at how he did it.

Mostly on our chargers which is a small part that we come across and which is a little annoying when it gets stuck somewhere at a time while trying to pull the cables. ferrite knuckle We will tell you its main function and what can happen in its absence. Let’s say right now, this cylinder, which we are angry about getting stuck somewhere, actually quite important serves a purpose.

We do not see these parts in new devices much, but this does not mean that they have disappeared. Instead, this cylinder appears internally. To briefly talk about its task without going into details, this cylinder prevents unwanted signals from entering.

Every device, whether internal or external, has to do this:

By regulating the current coming from the cable prevent energy loss ferrite knuckleresponsible for more efficient charging and power transfer. If you normally leave the electric current flowing through the cable unattended, you will likely lose power in the current due to electromagnetic interference.

But at this point, the Ferrite knuckle absorbs high-frequency electromagnetic waves. prevents power loss and provides a more efficient and stable flow. This small part, which we are used to seeing, performs this process, which can be quite critical for our electronic devices.

If we think about what would have happened if it had not happened, sizzle able to extract This is at high frequencies until your device breaks can go. For this reason, every internal or external device has a section that performs this vital function for the device.

Although they look like plastic from the outside, when you open these cylinders, there are two halves. ferrite ceramic cylinder appears before you. In addition to reducing electromagnetic interference, these cylinders, which prevent the signal emitted from devices such as mobile phones from affecting the electric current, are internally encountered in today’s devices.
