Inductor and the graphic symbol that electronic circuit pursues medium
Inductor is yuan of parts of an apparatus that electricity of a kind of magnetic field block up that uses coil generation changes to communicate in order to connect dc, block, basically use at wave of scale down, filter, resonance and magnetism deflexion to wait in electronic product.
In actual electron product or equipment, inductor is in with its actual exterior configuration installation various circuit board on, and pursue medium at the electronic circuit of this electron product or equipment in correspondence, inductor is replaced with appropriative graphic symbol, the inductor on circuit board and the graphic symbol that electronic circuit pursues medium are one to one correspondence.
Following plan institute show:
1, the graphic symbol that identifies inductor
Place laying a plan shows the graphic symbol that pursues medium in electronic circuit for common inductor, call circuit the symbol again. Can see, it basically is mixed by the thick wire of a few hemicycle two derivative lines are formed, the graphic symbol that the thick wire of a few hemicycle is inductor (the appearance that is equivalent to inductor interior coil simplifies graph) , two derivative lines are equivalent to two of inductor citing a base, by graphic symbol two end are extended, the electric line in pursueing with circuit connects, make electronic line.
2, the graphic symbol that knows different type inductor
In applying actually, the type of inductor is varied, corresponding graphic symbol also is distinguished somewhat, accordingly, understand the graphic symbol of the inductor of different type, the type of the inductor in giving electronic circuit to pursue to accurate identifying has important sense.
The graphic symbol of common inductor, appearance and function pursue as follows
3, the circuit that identifies inductor marks
Inductor is divided normally in the label in electronic circuit for two parts, one part is graphic symbol, the type of label inductor; Another part is a letter + number, label this inductor reachs main parameter in the name in circuit, serial number.
Graphic symbol (circuit symbol) the kind that demonstrated inductor, down-lead by graphic symbol two end are extended, the electric line in pursueing with circuit connects, make electronic line; The parameter information such as the name that the character marked to offer inductor normally, serial number and inductance quantity.
Know the label news that reads inductor:
The label of inductor basically has ” inductor name and serial number ” ” inductance is measured ” ” tolerance ” wait for pertinent information. Know the label news that reads inductor, very important to circuit of our analysis, overhaul.
The electric guide of the inductor in typical and harmonious circuit remembers following pictures
Typical and adjustable the circuit label of the inductor in oscillator circuit pursues as follows
