What should be paid attention to when selecting magnetic ring inductors

When we choose an inductor, we need to choose different inductors for different circuit boards. At the same time, we also need to see what the role of the inductor is in the circuit. Only in this way can we pre-select the desired inductor from many inductor types. So what should we pay attention to when using a magnetic ring inductor in the circuit? Today, let's learn about the precautions for selecting a magnetic ring inductor.

We all know the importance of inductor selection to the progress of a plan. If there is a problem with the inductor selection in the plan, it will seriously delay the construction period, waste manpower, funds, etc. and cause significant losses. When selecting a magnetic ring inductor, pay attention to the following points:

1. The inner diameter of the magnetic ring inductor is often larger than its own wire diameter, so as not to cause damage to the circuit board wire.

2. When we choose a magnetic ring inductor, we must also know what its role is in the circuit, that is, what kind of clutter should be resisted in the circuit, whether it is high frequency or low frequency, because this is about the selection of its important component-the magnetic core. There are two main types of magnetic ring inductor cores: manganese core and nickel core. Nickel core anti-interference magnetic ring belongs to high-frequency anti-interference. Its magnetic permeability generally ranges from tens to one thousand. Its magnetic permeability is low, and the loss is very small under high-frequency operation. It can work in high-frequency short waves. Manganese core magnetic ring inductor is opposite to nickel core. The selection of these two magnetic cores must be made by customers according to the actual application of magnetic ring inductor.

3. There is another important factor in the selection of magnetic ring inductor-wire diameter. The size of the wire diameter should be determined according to the actual current of the magnetic ring inductor.

In short, when selecting magnetic ring inductor, if the installation space allows, try to choose a long length, large outer diameter, and inner diameter that fits the connecting wire, so that the anti-interference performance will be stronger.

If the magnetic ring inductor in the circuit is not selected correctly, or it is not installed properly during installation, the magnetic ring inductor will not play the due anti-interference role, resulting in serious consequences of equipment damage. Therefore, the magnetic ring inductor should be used accurately.
