Embodiment in the present invention, those of ordinary skill in the art obtained under the premise of not making creative work it is all its
His embodiment, shall fall within the protection scope of the present invention.
It should be noted that in the absence of conflict, the feature in embodiment and embodiment in the present invention can phase
Mutually combination.
The invention will be further described in the following with reference to the drawings and specific embodiments, but not as limiting to the invention.
As shown in Figure 1, the utility model provides printed circuit board (Printed Circuit Board, PCB) formula power supply
Filter includes：
Inductor 1, including an at least conducting wire, conducting wire are wrapped on inductor 1 and a pin are arranged at the port of conducting wire
8.Inductor 1 is the element that electric energy can be converted into magnetic energy and stored.The structure of inductor 1 is similar to transformer, but
Only there are one windings.Inductor 1 has certain inductance, it only hinders the variation of electric current.If inductor 1 is logical in no electric current
In the state of crossing, it will attempt that electric current is hindered to flow through it when circuit is connected；If inductor 1 in the state of thering is electric current to pass through,
It will attempt to maintain electric current constant when circuit disconnects.Inductor 1 is also known as choke, reactor, dynamic reactor.Inductance is conducting wire
When inside passing through alternating current, alternating flux, the magnetic flux of conducting wire and the electric current for producing this magnetic flux are generated in the inner periphery of conducting wire
