2. Product Performance
In the mounting technology, it is mainly divided into active
components and passive components; and the power inductor is one of
the passive components; it can be divided into two ways: plug-in
and SMD; the so-called power inductor; The function of generating
power is also applicable to a surface mount component.
The power inductor is mainly composed of three main materials:
magnetic core, magnetic cover and copper wire; the magnetic core is
mainly made of ferrite material; it is made of iron-manganese-zinc,
nickel-zinc and other components with high magnetic permeability
sintered at high temperature; the composition of The copper wire of
the coil is also extremely important; the copper wire is generally
divided into enameled copper, copper-clad aluminum, etc.; in order
to make the power life of the chip inductor longer; the pure copper
wire with high temperature resistance must be used.

7.Structure and composition
Chip inductors are a commonly used electronic component. When the
current passes through the wire, a certain electromagnetic field
will be generated around the wire, and the wire in this
electromagnetic field will generate an induced electromotive
force-self-induced electromotive force, which we call
electromagnetic induction. In order to enhance electromagnetic
induction, people often wind the insulated wire into a coil with a
certain number of turns.
