FAQ

At present, the integrated inductor has many structural characteristics, such as high current, small volume, regular shape, flat, high installation efficiency, etc., which has become the mainstream trend of the society. For example, apple mobile phone, Samsung mobile phone, tablet, computer and many others have been replaced by the integrated inductor. However, one of the disadvantages of the integrated inductor is its high cost, so the magnetic adhesive inductor has become the dominant chip inductor.

In terms of technology, the integrated inductor belongs to the wound inductor, while the chip stack inductor belongs to the stack inductor; From the appearance, the size of integrated inductor 0603 is 7.4x6.6x3mm, while the size of chip stack inductor 0603 is 1.6 mm × zero point eight × 0.8(0603)。 The chip stack inductor is more obvious, thinner and lighter than the cuboid of integrated inductor; In terms of performance: the chip stack inductor has better heat dissipation and lower ESR value, but its current resistance is smaller than that of the integrated inductor, and its cost is lower than that of the integrated inductor.

Insulated conductor (enamelled copper wire) is generally used as the material of integrated winding, and the magnetic powder embedded in the base body is generally reduced iron powder, carbonyl iron powder, alloy powder, etc. Its current characteristics and price ratio are generally based on the inductance, current characteristics and corrosion resistance

The components used in the car are divided into front loading and back loading. The front loading requirements are very strict, not only for the production enterprises, but also for the specific products. The back loading is much better. The inductors with large current and large inductance are mainly used, such as chip integrated high current inductor and traditional assembled power inductor.
