What matters should be paid attention to in the selection of magnetic ring inductance
When we choose an inductance, we need to choose different inductances for different circuit boards, and we also need to look at what the inductance does in the circuit. Only in this way can we pre-select the desired inductance among many types of inductances. So what do you need to pay attention to when you need to use a magnetic ring inductance in a circuit? Today, let's learn the precautions for the selection of magnetic ring inductance. We also all know the importance of inductor selection to the process of a program. If there is a problem with inductor selection in the program, it will seriously delay the construction period, waste manpower, and cause heavy losses. The following points should be paid attention to when selecting the magnetic ring inductance: 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 selecting magnetic ring inductance, we also need to know what its role is in the circuit, that is, which clutter should be resisted in the circuit, whether it is high frequency or low frequency, because it is about the choice of its important components - magnetic core. There are two main types of magnetic cores: manganese cores and nickel cores. The nickel core anti-interference magnetic ring is a high-frequency anti-interference. Its magnetic permeability is generally from tens to one thousand. Its magnetic permeability is low, and the loss is very small under high frequency operation. For short-wave operation, the manganese core magnetic ring inductance is opposite to the nickel core. The choice of these two magnetic cores should be selected by the customer according to the actual application of the magnetic ring inductance. 3. There is another important factor in the selection of the magnetic ring inductance - the wire diameter. The size of the wire diameter should be determined according to the actual current of the magnetic ring inductance.
In short, when selecting the magnetic ring inductance, if the installation space allows, try to choose a long length, a large outer diameter, and an inner diameter that fits the connecting line, so that the anti-interference performance will be stronger.
If the magnetic ring inductance in the circuit is not selected correctly, or is not installed properly during installation, the magnetic ring inductance will not play its due anti-interference effect, resulting in serious consequences of equipment damage. Therefore, it is necessary to use the magnetic ring inductance accurately and accurately.
