Believe that many people to professional plastic magnetic particles are seen in its input cable, output cable, charging battery cable is covered with a great magnetic ring, in the supervision of the parts above see a small magnetic ring, then will want to know why this thing is used, the following is a simple detailed introduction.

Professional plastic magnetic mould used to suppress EMI interference, on the cable contains power plug on the peak for the noise and interference, it has to make electronic products achieve the electromagnetic compatibility (EMI/EMC) and static electricity charge and discharge of the corresponding standard, can be applied to a multi-core cable or a bunch of multicore cable wear in among them, wear a can enhance its actual effect. Generally, the characteristic impedance value of 25MHz and is used to consider the adsorption characteristics of magnetic ring beads.

Anti-interference magnetic ring demarcation

(ElectromagneticCompatibility) EMC electromagnetic compatibility and refers to some electronic product doesn't interfere with other machinery and equipment, at the same time also will not suffer the harm of other facilities. Electromagnetic compatibility is one of the most important indexes of product quality as well as safety factor. Safety factor relates to personal safety and assets, while electromagnetic compatibility relates to personal safety and ecological environment protection.

Why anti-jamming magnetic rings?

Professional motor injection magnet works at a very high frequency, so there are a lot of indoor space stray electromagnetic induction interference signals in the equipment, and the compressive strength of the signal is many times to tens of times of the equipment outside. No magnetic ring cable is not the use of interception strategy, so this cable becomes an effective wireless antenna, accept a variety of high-frequency signals in the surrounding environment, this signal accumulation in the original transmission signal, and even change the original transmission of effective signal, very easy to occur.
