Background technology
With expanding economy and the progress of society, inductor is also more and more appeared in our daily lifes, but
It is but seldom well known.It is reported that, inductor is the element that electric energy can be converted into magnetic energy and be stored.Inductance
The structure of device is similar to transformer, but only one of which coil.Inductor has certain inductance, and it only hinders the change of electric current.
If inductor is in the state of no electric current passes through, it will attempt to hinder electric current to flow through it when circuit is connected；If inductor
In the state of having electric current to pass through, it will attempt to maintain electric current constant when circuit disconnects.Inductor also known as choke, reactor,
Dynamic reactor.And so-called surface mount inductor, it applies to surface mounting technology as other chip components and parts
A new generation without lead or short leg miniature electronic part.The solder side of its exit is at grade.
