Abstract
The utility model discloses an integrated forming chip inductor which comprises a seat body, a winding body and pins. The integrated forming chip inductor is characterized in that the seat body is a metal magnetic powder casting body; the winding body is arranged inside the seat body; the winding body is a coil; two ends of the coil are respectively connected with the two pins; and the pins are directly adhered to the surface of the seat body. As an autogenetic closed magnetic circuit structure and a soft magnetic material are adopted, the integrated forming chip inductor has the excellent characteristics of large current and large power resistance, low loss, high impedance, no noise, high saturation magnetic flux density, etc. Moreover, the integrated forming chip inductor has small size and light weight. The size and the weight of a chip inductor element are only about one tenth of the traditional inserting element; therefore, the integrated forming chip inductor is easy to realize batch and automatic induction production.
Description
Technical field
The utility model belongs to inductance manufacture craft field, is specifically related to a kind of one-body molded chip inductor.
Background technology
Integrated circuit (IC) is the core of all electronic products, modern society is accompanied by advancing by leaps and bounds of electronic product technology, demand and specification requirement to the electronic component of forming IC have also reached a peak, passive device is the important component part of circuit, it is characterized in that not influencing the signal essential characteristic, only make signal pass through and the circuit element that do not changed.Passive device is mainly contained the three major types product: resistor, inductor and capacitor, wherein, inductor is the most important thing.Coil is called inductance with the ability of magnetic approach storage power, and this coil is called inductor.The inductor major function is the noise that prevents in electromagnetic interference, the filter current, and its scope of application is very extensive, for example motherboard, computer, scanner, power supply unit, switch etc.
The trend of electronic product is constantly to pursue miniaturization, traditional inductance volume is big, quality heavy, frangible, noise is big, and its manufacturing process can not realize production lotization, automation, production efficiency is low, the cost height.Previously used perforation plug-in unit element can't dwindle, and particularly extensive, high integrated IC has to adopt the surface patch element.
Summary of the invention
At above problem, the utility model is to provide a kind of one-body molded chip inductor, and this inductance adopts and has closed magnetic circuit structure and soft magnetic material of one's own, and volume is little, in light weight, reliability is high, shock resistance is strong, the welding point defect rate is low.
The technical solution adopted in the utility model is: a kind of one-body molded chip inductor, comprise pedestal, winding body, pin, it is characterized in that: pedestal is a metal magnetic powder die-casting body, the winding body is positioned at pedestal inside, the winding body is a coil, the coil two ends are connected with two pins respectively, and pin directly is attached to the pedestal surface.
The beneficial effects of the utility model are: good characteristic such as the utlity model has can anti-big electric current, high-power, high energy storage, high impedance, noiseless, high saturation magnetic flux density, and volume is little, in light weight, the volume and weight of inductance surface mount elements has only about 1/10 of traditional inserting element, equipment such as motherboard, computer, scanner be can be widely used in, inductance production lotization, automation are easy to realize.
Description of drawings
Accompanying drawing is explosion views of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
With reference to accompanying drawing, a kind of one-body molded chip inductor, comprise pedestal (1), winding body (2), pin (3), it is characterized in that: pedestal (1) is a metal magnetic powder die-casting body, winding body (2) is positioned at pedestal (1) inside, winding body (2) is a coil, and the coil two ends are connected with two pins (3) respectively, and pin (3) directly is attached to pedestal (1) surface.
By above execution mode, the utility model owing to adopt has the diversity that closed magnetic circuit structure and soft magnetic material are selected for use of one's own, therefore has the good superimposed characteristics of anti-the AC-to-DC, the inductance volume is little, in light weight, the volume and weight of surface mount elements has only about 1/10 of traditional inserting element, reliability height, shock resistance are strong, the welding point defect rate is low, and are easy to realize inductance production lotization, automation.
