How to choose the magnetic ring?EMC anti-interference related terms

2023-11-17
"How to choose the magnetic ring","How to choose the magnetic ring"I usually first understand the use of the customer's magnetic ring,the frequency of use and so on.
Magnetic Ring
Here I simply analyze,such as:when encountering interference,generally use amorphous magnetic ring,manganese-zinc magnetic ring or nickel-zinc magnetic ring,of course,these three magnetic rings use different frequency segments.When high-frequency interference is used,the nickel-zinc magnetic ring is selected.How big the magnetic ring is used for the large wire,the inner hole must be paid attention to,the wire thickness and the inner hole of the magnetic ring must be just right,too big to wear,too small to leak magnetic,still There are injection molds that are slightly larger than the magnetic ring size,but do not make the gap too large,so it is not easy to damage the mold during injection molding.In addition,when the performance is not strong,the wire diameter is so large,then the outer diameter and the inner hole are unchanged,but the length is selected to be a longer magnetic ring.Generally,the selection of the magnetic ring is preferred to"the outer diameter is large,the inner hole is small,and the length is long".The larger the cross-sectional area ofthe magnetic ring,the better the effect.
