How to quickly identify ring inductance good or bad?

Toroidal inductor We want to give you a simple introduction, recently found that many people in the consultation found that the ring magnetic ring inductance how to identify good or bad problems. In this article, we will learn how to distinguish the mass of a toroidal inductor.

We can also measure the quality of inductor by learning some related instruments. For example, by measuring the consistency of inductors of the same data type, the mass of the magnetic core can also be seen for itself; We can also choose to judge the quality of inductance by analyzing the test current. The same magnetic core, but some of the working current is not very good, and some of the current ability is very poor, under the same current, that is to say, they have different inductive value decline rate, good magnetic core's inductive value decline rate is relatively low cost.

It can also be identified by core damage: if there is a gap in the core, if there is a bump.

If enamelled wire is damaged, what parameters will be affected by magnetic core damage?

Bar inductor cannot be used when enamelled wire is damaged. As the enamelled wire is damaged, it may cause a short circuit if the enamelled wire is near, so the damaged enamelled wire cannot be delivered to the customer. If the enamelled wire is damaged more, the production process is also clear, and the production process needs to be further discussed.

If the core damage is only a little, it will not matter, but the damage should not be too great. The core damage rate should not be very high. If the damage rate is high, the inductance quality is relatively poor. If the magnetic core is damaged, the inductive quality is poor.

Sometimes we in China will find some inductors wrapped with tape. What is the teaching effect of this? If the tape is damaged, will it affect the inductance?

The tape on the outside of the inductor actually does the maintenance. If the tape on the outside of the inductor breaks, its maintenance effects will be lost, so it can't be broken.
