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.

5.Features
Various high power inductors are superior to be high saturation for
surface mounting
6.Application
(1).Power supply for TVR,OA equipment,audio ,LED television
(2).Communication equipemnts,DC/DC converters,etc.
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.
