Detailed explanation of the wound chip inductor structure

Winding inductance structure components?

Winding inductance is mainly composed of a skeleton, a winding and a magnetic material.

Type A is a structure with a skeleton winding inside, a magnetic material shielded outside, and a plastic molded package; Type B is a rectangular skeleton winding (the skeleton has a ceramic skeleton or a ferrite skeleton), and both ends are used for welding. The C type is an I-shaped ceramic, aluminum or ferrite skeleton, and the welded portion is at the bottom of the skeleton.

What are the characteristics of the wound inductor structure?

The A-type structure has magnetic shielding, which has little influence on other inductors and can be mounted at a high density; the B-size is the smallest and the C-size is the largest. The operating frequency of a wound chip inductor depends primarily on the skeleton material. For example, an inductor using a hollow or aluminum skeleton is a high frequency inductor, and a ferrite skeleton is a medium and low frequency inductor.

What line is used for winding inductance?

The wound chip inductor is made of an enameled wire wound around the skeleton, and has different inductance and Q value according to different skeleton materials and different numbers of turns.
