Description
Technical field
The utility model relates to field of electrical components, particularly a kind of circuit board inductor.
Background technology
Inductor can be the element that magnetic energy stores electric energy conversion.The similar of inductor in transformer, but only has a winding.Inductor has certain inductance, and it only hinders the change of electric current.If inductor is under the state not having electric current to pass through, during circuit ON, it will attempt to hinder electric current to flow through it; If inductor is under the state having electric current to pass through, circuit disconnect time it will attempt maintenance electric current constant.Inductor is also known as choke, reactor, dynamically reactor.Inductance can be made up of conducting material wound around magnetic cores, typical in copper cash, also magnetic core can be removed or replace with ferrimagnet.The core material higher than the magnetic permeability of air can constrain in magnetic field around inductance element more closely, thus increases inductance.Inductance has a variety of, mostly makes with outer enamel coil encircling ferrite bobbin, and some protection inductance is placed in coil in ferrite completely.The core of some inductance elements can regulate.Inductance size can be changed thus.Small inductor can directly be etched on pcb board, by a kind of method of laying helical trajectory.Little value inductance also can in order to manufacture the same manufacture technics of transistor in integrated circuits.In such applications, aluminum interconnecting is often used as conductive material.Which kind of method don't work, and the constraint based on reality is applied maximum still one and is called the circuit of " gyrator ", and it shows the characteristic identical with inductance element with an electric capacity with active member.Form through a conventional wire through magnetic post or magnetic bead for the inductance element every high frequency.
Utility model content
