What is the function of the terminal wire harness with magnetic ring? Some terminal wire harnesses will have a magnetic ring wrapped in foam. In fact, it has some special functions.
Firstly, the terminal wire harness with magnetic ring can resist high-frequency interference, which can either flow out of the device itself or enter from the outside. The energy of the high-frequency signal will be absorbed by the ferrite core and converted into heat to be emitted.
Secondly, absorbing magnetic ring is also called ferrite magnetic ring. It is usually used in detachable separation magnetic ring. It is also a commonly used anti-jamming component in electronic circuits. It has a good suppression effect on high frequency noise. This is why many electronic products use magnetic rings.
But is it not good to have a magnetic ring terminal wire? In fact, it is not the case. The use of magnetic rings is more to prevent external high-frequency signal interference, and the use of shielding layer can also achieve the effect of shielding high-frequency signal interference, so if it is only judged by the presence or absence of a magnetic ring, it is It is too singular and not very reasonable.
