The difference between inductor and ordinary inductor| GETWELL

Friends who understand inductors know that there are two kinds of inductors in the classification of inductors: shielded inductors and unshielded inductors. In the previous article, we also mentioned these two kinds of inductors, but did not compare them together. Today, inductor manufacturers come with you to understand the difference between shielded inductors and unshielded inductors.

The difference between shielded inductors and unshielded inductors

You think all the surrounding inductors are shielded inductors? A shielded inductor is an inductor surrounded by a magnetic core. Not all inductors surrounded by cores are shielded inductors, such as GNL inductors, which are also surrounded by cores but not shielded. It is important to distinguish shielded and unshielded inductors externally to determine whether the inductor is surrounded by a magnetic core. Attack rate of inductance

Generally speaking, unshielded inductance enameled wire is exposed outside without magnetic shield cover; Shielding inductor with magnetic shielding, good EMI resistance, reduce the electromagnetic interference of the inductor to the outside world, reduce the interference of the electromagnetic field generated by the circuit to other components.

In fact, there is a big difference between shielded inductance and unshielded inductance is that the shielded inductance is a closed magnetic circuit, while the unshielded inductance is an open magnetic circuit. The so-called closed magnetic circuit means that the whole closed magnetic circuit is composed of magnetic materials, while the open magnetic circuit means that there is an obvious air gap in the magnetic circuit.

Not only are they different, but there are some similarities. Their volume is generally small, the surface is easy to stick, suitable for automatic production, according to the different requirements of customers to produce different size specifications for customers to choose. Relatively speaking, the unshielded inductor has better welding resistance and heat resistance, suitable for general welding and reflow welding, with lower cost.

Integrated inductor and common inductor difference

The precision of integrated inductor is slightly higher than that of ordinary inductor. In general, integrated inductors are only 20% accurate, while our other inductors are 10% accurate. Even some inductors have better accuracy, such as 5%, compared with 20% for integrated inductors. Since the precision of integrated inductor is poor, why occupy a larger market share?

This is because integrated inductors have advantages in terms of inductance values. It has a narrow range of sensing values. Generally, its inductance value is less than 100uH, and some types of integrated inductors can reach inductance value less than 1uH. Tapping rate inductor quoted

We know that the integrated inductance and ordinary inductance in numerical sense, the difference between the integrated inductor current is bigger, if their number sense is 10 er, an integrated inductance current can do a lot of, the average inductor current is small, so some products of numerical requirements is not high, but in the case of large current, the application of the integrated inductance is more, such as computer and other fields.
