How to choose the magnetic ring specifications and models, often there are many customers who have just developed or just contacted how to select the magnetic ring, said some electromagnetic interference with electrical appliances and cables, resulting in communication equipment crashes and other issues. Then how to choose the magnetic ring specifications and models.

In the selection of the magnetic ring for injection molding, how large the magnetic ring is used, the inner hole must be noted, the wire thickness and the inner hole of the magnetic ring must be just right, too big to wear, too small to leak magnetic, and injection mold It should be slightly larger than the size of the magnetic ring, but do not make the gap too large, so it is not easy to damage the mold during injection molding. In the case of its frequency, the frequency is not up, the wire diameter is so large, then the outer diameter and the inner hole are unchanged, but the length should be longer. Generally, the selection of the magnetic ring is preferred to have a large outer diameter, a small inner hole, and a long length. The more the magnetic ring size contains the material, the better the effect.

The method of selecting a flat magnetic ring, the inner hole of the flat magnetic ring is flat and wide, and the length and outer diameter appear flat, so it is called a flat magnetic ring or a flat magnetic ring. These types of models are generally used on the cable. According to the width and thickness of the cable, the width of the cable and the flat magnetic ring must match. It is not suitable for wearing, and it is too loose to get its characteristics. When selecting, first measure the lower line with a caliper and select it.
